Greetings,

Been searching, but have not acquired an answer to my problem, so I resolve to you dear community.

I have a LSI SAS card, AOC-USAS2-L8E to be exact. Been running kernel 3.4.9 and using the "LSI MPT Fusion SAS 2.0" driver without issues. Recently I messed up when updating world and accidentally depcleaned the kernel-sources, rendering myself unable to recompile the kernel which caused all sorts of hell.
So I moved on to kernel 3.8.13 but when attempting to boot it interrupted. Actually, this ->http://img22.imageshack.us/img22/3613/m198.jpg happens. So before I begin tinkering, I shut down the computer and pull the power cord to my hotswap-bay, since I suspect finding the problem might take a few reboots. Next reboot everything works. Since then I've confirmed my suspicions, this only happens when the drive-bay is connected, i.e. when the LSI card detects the disks and only for 3.8.13. In this particular case, the 3.4.9 kernel still works.
Regarding the picture.. I hope it's not something unfixable related to SMP since I'd really like to utilize both cores efficiently..

I can't really pull any logs from this since none (that I know of) has started before it interrupts. Well, besides kexec crash dump, but that's a hassle.

Tried to post the .config in a code box, but seems it was a bit to much text.. Editing it atm, updating soon.

If there's anything else you need to know, just ask and I'll try to retrieve it.

Best regards,
Marc

mount_block_root, as seen is your screenshot under panic, means that it is unable to mount the root block; this can be due to multiple reasons:

:arrow: An incorrect root= parameter, please check this.
:arrow: The file system not built into the kernel or initramfs, please check this too.
:arrow: One of the *TMPFS* not set to Y; though, those seem to be okay.
:arrow: The controller not compiled into the kernel or initramfs; though, that seems to be okay too.

If neither of the first two fixes this, and nobody else has an idea here; please file this as a bug at https://bugs.gentoo.org so we can look deeper into this.

Thank you for your reply!

Here's my fstab:
Code:
default 0
timeout 0
#splashimage=(hd0,0)/boot/grub/splash.xpm.gz
fbcon=scrollback:256K
title Gentoo Linux Entertainent Server
root (hd0,0)
kernel /boot/kernel_3.8.13 root=/dev/sda3 video=uvesafb:mtrr:3,ywrap,1280x800-24@60

#video=vesafb:mtrr:1,ywrap vga=ask vga=0x0361

Though I don't see how that could be a problem since the system boots without the disks connected.. *edit* By "disks" I mean the storage disks in my hotswap-bay. I've SSD's for OS connected directly to the motherboard.

*edit 2*
This might seem dense, but since I lack knowledge here, I have to ask. This must be me making a bad interpretation, you're not saying the controller driver should be compiled into the initramfs? Because that I do not know how to do.

Ah, when you connect them, the order of sda / sdb swaps around; so, you will want to specify root as UUID instead.

As root, execute `blkid` or alternatively `ls -l /dev/disk/by-uuid/`; then use the value for /dev/sda3 in /etc/fstab (as per https://wiki.gentoo.org/wiki/Fstab) as well as use the UUID part after root=PARTUUID= (as per http://lxr.linux.no/linux+v3.8/init/do_mounts.c#L180), although I think this recently changed to root=UUID= so for example use something like "kernel /boot/vmlinuz root=UUID=00000000-0000-0000-0000-000000000000". I haven't done this myself yet; so, I don't know what the definitive guide to follow is, but this should at least clarify why it no longer boots.

Aaaah of course! Thank you!
