 |
|
Greetings,
I've had a similar issue with this, i believe i'm missing a kernel option somewhere.
I have a Toshiba Tecra R840-10T with the following upgrades: 8GiB of RAM, a Kingston SHSS37A240G SSD in the regular HDD bay and the original Toshiba MK5061GSYN HDD (actually the original was a Seagate replaced in warranty) in the optical bay.
/boot is the first partition in the SSD, ext2; swap is second; the third is LVM, with / (XFS), /usr, /usr/src, /var (ext4).
(The HDD has /home and /opt, both ext4.)
Since i'm using LVM, a separate /usr and lilo, i need an initrd, which i generated with genkernel using --lvm.
However, when booting, i don't see LVM mentioned in the modules as they're loaded and the boot process dies with:
| Code: | Block device /dev/myVG/myRootLV is not a valid root device...
Could not find the root block device in . |
Which leads me to conclude i'm missing something in the kernel. I believe i have all the related SATA flags on, i don't think there's anything special for using an SSD.

append="root=/dev/myVG/myRootLV"
initrd=/boot/initramfs-genkernel-x86_64-4.1.15-gentoo-r1 |
Can i replace that /dev/sda with a /dev/disk/by-id entry?
/boot/vmlinuz is a symlink to /boot/vmlinuz-4.1.15-gentoo-r1
Can anyone tell me which are the required kernel drivers for this SATA? I didn't find anything "C200" in the kernel (nor did i find the modems, where are they?).
Edit 1: this same laptop booted a Slackware64 14.1 with a single / and lilo off of the SSD, so i don't think it's a hardware problem.
Edit 2: my .config

Ok, guess i solved the boot problem.
The error message was
| Code: | >> Activating mdev
>> Loading modules
:: Loading from pata : pata_oldpiix
:: Loading from sata :
:: Loading from scsi :
:: Loading from usb :
:: Loading from firewire :

>> Determining root device ...
!! Block device /dev/myvg/mylv is not a valid root device...
!! Could not find the root block device in . |
After fiddling some more in the kernel i ended up with this .config.
I generated the initrd with:
| Code: | | genkernel --color --keymap --lvm --e2fsprogs --disklabel --busybox --firmware -- install initramfs |
(more stuff than needed most likely). I also added dolvm to the append line in /etc/lilo.conf
This led to lilo booting (as it was before) and loaading an enormous amount of modules (well at least that's what i think all the ........ dots are, some 7 lines of'em). And then i got the login prompt.
Only i kinda forgot e1000 and iwlwifi is a module, but i logged into the system. Other quirks will come.
Edit as a heads-up for not having network interfaces on boot at all, the wired gigabit interface uses e100e (PCIe), not e1000 (which i did have compiled in). I found this via lspci -k from the livecd.
Edit 2 and the wireless interface should be loaded as a module. Also, --lvm suffices for genkernel. |
