 Posted: Sat May 06, 2023 5:15 pm Post subject: Unable to boot kernel 6.x with Threadripper Pro [solved] |
 |
|
Hello,
i have been on Gentoo for many years but currently i'm stuck at switching from Kernel 5.x to 6.x.
No matter what i do, it got stuck right after grub with the message "booting kernel 6.1.19-gentoo". Kernel 6 build with make oldconfig or fresh config, i could not get past this boot message. Caps Look still working, no "halt". Tried as well with minimal Grub appends...
Any Kernel < 6.x boots just fine, even 4.x kernels.
Is it just me or got smth major changed with kernel 6.x? How can i trace the problem? I don't want to stay at 5.x forever 
(gentoo-sources)
Help much appreciated! 
Thanks

Same happens with latest "gentoo-kernel-bin:6.x" even when using prebuild initramfs - in that case it got stuck with "loading initramfs".
So i assume its not about my kernel config. What else could it be?

linux-firmware
?

MaDDeePe,
Lots of people have had issues with framebuffer settings: see the wiki article.
If that's no help, perhaps put your .config file on pastebin or similar for us to look at.

Hi, with kernel 6.1.19-gentoo i installed linux-firmware (with correct softlink into kernel sources) and wrote the path for Gen 17h CPU into kernel as well. Doesnt change anything.
But i just got another hint from this link: https://superuser.com/questions/1771347/no-console-output-with-linux-6-x-with-asus-wrx80e-sage-mb
It turns out that my grub appends: | Code: | | GRUB_CMDLINE_LINUX="linux amd_iommu=on iommu=pt video=efifb:off vfio-pci.ids=10de:2208,10de:1aef" |
*could* have something to do with it. I needed them because i wanted to play games in this machine virtualizing in windows (PCI-Passthrough)
Just now i found out that the precompiled bin-kernel boots without "video=efifb:off". Also, its seems that i don't need "amd_iommu=on iommu=pt" anymore? Maybe the latest 5.x kernel and virt-manager handles all that stuff now, i can boot that machine up without all that parameters!
Nonetheless, "gentoo-sources-6.1.19" is still stuck even with empy CMDLINE_LINUX.
I assume this is Motherboard related with something about UEFI / Secureboot.
Ill post my results if i cant solve it. |

By itself?
Did you or something else modify
/etc/default/grub
?
Yes
video=efifb:of
seems highly suspect.
Remove it and update grub please.
Also for the time being plz boot with gentoo-kernel-bin and an initramfs.

This helped! No clue why 5.x kernel was booting with this misconfigured, 6.x isn't.
Thanks!!!! |
