[arch-general] Update to 2.6.34.3-1 & LTS 2.6.32.18-1 killed dmraid box??

[David C. Rankin]

Guys,

	This one caught me by surprise. I have my test server that I update before 
updating my regular server. It is based on a MSI K9N2 board (MS-7374) with a 
Phenom 9850 proc & 8G of ram. The box has 2 dmraid arrays:

[22:00 ecstasy:/mnt/arch] # dmraid -r
/dev/sdd: nvidia, "nvidia_baaccaja", mirror, ok, 1465149166 sectors, data@ 0
/dev/sdc: nvidia, "nvidia_fdaacfde", mirror, ok, 976773166 sectors, data@ 0
/dev/sdb: nvidia, "nvidia_baaccaja", mirror, ok, 1465149166 sectors, data@ 0
/dev/sda: nvidia, "nvidia_fdaacfde", mirror, ok, 976773166 sectors, data@ 0

[22:00 ecstasy:/mnt/arch] # dmraid -s
*** Active Set
name   : nvidia_baaccaja
size   : 1465149056
stride : 128
type   : mirror

	The kernel updates applied tonight were:

[2010-08-16 20:13] upgraded kernel26 (2.6.34.2-2 -> 2.6.34.3-1)
[2010-08-16 20:13] upgraded kernel26-headers (2.6.34.2-2 -> 2.6.34.3-1)
[2010-08-16 20:14] upgraded kernel26-lts (2.6.32.17-2 -> 2.6.32.18-1)

	Both completed successfully. The pacman.log info is here:

http://www.3111skyline.com/dl/Archlinux/bugs/pm-updt-8-16.txt

	After boot to the normal 2.6.34 kernel, the box kept automatically rebooting 
itself - WTF? So I booted to the LTS kernel, which booted this time and rebuilt 
the initramfs file with:

/sbin/mkinitcpio -k 2.6.34-ARCH -c /etc/mkinitcpio.conf -g /boot/kernel26.img

	It completed successfully. Rebooting resulted in an error that the the 
partitions were corrupt. So I attempted to boot back into the LTS kernel. It 
failed as well?? So I rebooted into suse 11.0 which is on the other array. The 
box booted into suse without any problems. I then mouted the Arch array and the 
partitions are fine. (that's where the raid info above came from).

	I don't know what is going on here. Kernel updates on this box have always been 
uneventful. Tonight all hell broke loose. What could have caused Arch to report 
the partitions were bad? More important, what do I do to get Arch back? I 
believe I have the correct modules in mkinitcpio.conf (they are the same ones I 
have had in the conf file since I first loaded Arch with the 200902 install 
media in March '09). Here is the lspci info (running suse):

	The raid controller is the standard nvraid soft raid controller:

	What say the gurus? (Tobias what could have changed here?) Any help would be 
greatly appreciated. I'll keep dorking with it, but I'm at a loss here...
