 Posted: Tue Apr 09, 2024 9:18 pm Post subject: [solved] 6.6 kernel cannot boot after profile upgrade (LUKS) |
 |
|
Hi guys.
I moved from 17.1 to 23.0 profile last weekend. As part of upgrade process, the latest kernel was recompiled. However, I can't longer boot the system. I am using LUKS encrypted root partition and during boot process I am asked for passphrase. I can type in the passphrase, but boot process stands still, only the cursor is blinking. There are no error messages. Same kernel worked fine before profile upgrade.
Previous kernel 6.6.16 still works normally (but was not recompiled during profile switch).
I am using sys-kernel/gentoo-kernel (initramfs strip -debug -generic-uki -hardened -modules-compress -modules-sign -savedconfig -secureboot -test) with default config. Initramfs is built with dracut. The only thing I noticed is that size of initramfs image differs in 1MB:
| Code: |
# du -sh /boot/*
260K config-6.6.16-gentoo-dist
260K config-6.6.21-gentoo-dist
144K EFI
14M grub
12M initramfs-6.6.16-gentoo-dist.img
11M initramfs-6.6.21-gentoo-dist.img
14M intel-uc.img
9.1M System.map-6.6.16-gentoo-dist
9.1M System.map-6.6.21-gentoo-dist

Perhaps this is not the answer you seek, just my two cents.
For me, dracut stopped generating working initramfs with upgrade to 23.0 profile.
I switched to genkernel:
| Code: | | genkernel --lvm --luks initramfs |
If you do find out what changed, please let know. genkernel takes forever, I would gladly go back to dracut |

@erg_samowzbudnik
Thank you, but I would like to avoid using genkernel, primary because I want to use Portage to perform the upgrades as part of regular upgrade procedure.
I have used lsinitrd tool to inspect both initramfs images. It is difficult to compare the diff line by line, but this is the main difference:
| Code: |
Image: initramfs-6.6.21-gentoo-dist.img: 12M
========================================================================
Version: dracut-060
Arguments: --force --verbose --kernel-image '/usr/src/linux-6.6.21-gentoo-dist/arch/x86/boot/bzImage' --no-uefi
dracut modules:
crypt
dm
kernel-modules
kernel-modules-extra
rootfs-block
terminfo
udev-rules
usrmount
base
fs-lib
shutdown
|
| Code: |
Image: initramfs-6.6.16-gentoo-dist.img: 12M
========================================================================
Version: dracut-060
Arguments: --force --verbose --kernel-image '/usr/src/linux-6.6.16-gentoo-dist/arch/x86/boot/bzImage'
dracut modules:
crypt
dm
kernel-modules
kernel-modules-extra
rootfs-block
terminfo
udev-rules
usrmount
base
fs-lib
shutdown
|
So dracut for 6.6.21 passes --no-uefi option. I also did try to build manually image, but even with this manually generated image the result it the same - nothing happens after passphrase input. Following command was used:
| Code: |
dracut --force --verbose --kver 6.6.21-gentoo-dist --hostonly
|
I am not sure where to proceed from here? Is it possible that because some binary packages were used during upgrade process, that there is "something" that is causing this? Any tip is appreciated.
I also noticed another issue on shutdown/reboot - I have to switch to another shell and poweroff manually. Shutting down or rebooting from Plasma leaves the black screen with blinking cursor. There is this message in /var/log/messages:
| Code: |
/usr/bin/power[16228]: Failed to execute /usr/bin/poweroff: No such file or directory |
^ Solved the issue with poweroff/reboot. Recompiled sys-auth/elogind as replacement for binary package that was pulled during profile switch. Not sure if that is real cause of the issue, but it solved it for me. |

Experimentally, try the binary version of the gentoo-kernel. If that doesn't work as intended, ditch all the binary packages and compile those locally.

This looks like fallout from confusion over split-usr versus merged-usr. The traditional location of poweroff is /sbin/poweroff. Invoking it from /usr/bin can work if the system is merged-usr, since everything from /sbin will have been dumped into /usr/bin. Otherwise, it needs to be invoked from its actual path, or found via a search of $PATH. |

Gentoo-kernel-bin did not solve it, the issue remained. In the end I picked only packages from "sys-" categories and reinstalled them from source in order to replace binaries. That solved the issue for me (it was around 60 packages in total).
Thank you all for the feedback.

Does this mean that it is not good idea to use binaries for split-usr profiles yet (or ever)? |

I don't think so. In my experience it's dracut that is the problem, most of the times.
Example: I just recently switched from genkernel to UKI, including generating my own secure boot keys, and now I'm using dracut as well. I also enabled secure boot on my system firmware. Genkernel was not very easy to setup in this scenario, and it was actually the missing continued development of genkernel that made me switch in the first place.
So, now I'm a new user to dracut. As it was, with the switch to UKI (unified kernel images) and secure boot, I also created a new ESP (EFI System Partition) + XBOOTLDR partition (both VFAT) configuration (before it was ESP as VFAT + /boot as ext2/ext4 minus journal).
I already had a working UKI, and systemd-boot picked it up, everything worked. In the UKI I'm using dracut. So, I had removed /boot and added XBOOTLDR. As it later turned out to be the case this only worked because the XBOOTLDR partition was already in place when I created the UKI.
Now, booted with the working kernel and having removed the old ones I couldn't use anymore anyway, I also recreated the ESP, so it had a new volume ID, you know, this 12AB-34CD kind of 1980's version of a UUID. So, what happened now was that the UKI refused to boot, specifically the dracut part: it kept saying it cannot find the ESP (the old one, with the old volume ID). PLEASE ANYONE TELL MY WHY THIS IS NECESSARY? The UKI was already loaded, and dracut should have just ignored this, because in my fstab the new ESP was defined anyways.
The workaround was the funniest: I just created a 1 MB VFAT ESP partition on an USB stick (or an external USB HDD, cannot remember) and gave it the missing volume ID that dracut was looking for. There was nothing on that partition. Now I could boot into my system again, but I had to recompile the kernel image, re-run install-kernel and everything to get an updated UKI.
How stupid is that?!?
And now I have the same issue: dracut refuses to boot when the image is created while a bcachefs filesystem is mounted. I tried bcachefs as my new /var partitions filesystem and I am very happy with it. All previous UKIs work fine. Every new one fails, it simply reboots. I have to unmount my bcachefs, then create the new kernel UKI, and then dracut can boot WITH the bcachefs now in place from my fstab.
So you see: it really is dracut, that is to blame. Often. Most of the time.
I think, dracut is too big. It checks too much. Hence all those errors.

I think it would be best to only use binaries built for the same type of usr you have locally. When on a merged-usr system, use binaries built for merged-usr. When on a split-usr system, use binaries built for split-usr. In many cases, you can probably get away with using the "wrong" type, and using binaries that expect split-usr will probably work on merged-usr, assuming they do not suffer file collisions during installation. You were trying to use a binary that expected merged-usr[1], but running it on a split-usr system. The safest course is not to use foreign usr binaries.
[1]: More specifically, it used the wrong path to something, and because merged-usr dumps everything into one directory, people on merged-usr systems can get away with using the wrong path. |

I am not sure I get this... 
My old profile was "default/linux/amd64/17.1/desktop/plasma". Respecting the profile upgrade table https://wiki.gentoo.org/wiki/Project:Toolchain/23.0_update_table, correct new profile is "default/linux/amd64/23.0/split-usr/desktop/plasma" and binhost directory is "amd64/binpackages/23.0/x86-64-v3".
What did I do wrong? How can I know if the binary expects split-usr or merge-usr? |

| That seems correct to me. Did you get /usr/bin/power from the binhost in that directory? What package provides /usr/bin/power? Perhaps whoever built it is now always configuring for merged-usr paths, even when building on a split-usr profile. |

I am not sure. There is not/was not one on my system. Some Google result showed me that it could be related to elogind, so I recompiled it considering the elogind package at that moment was a binary one. It solved the issue. |
