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 status : ok subsets: 0 devs : 2 spares : 0 *** Active Set name : nvidia_fdaacfde size : 976773120 stride : 128 type : mirror status : ok subsets: 0 devs : 2 spares : 0 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: 00:09.0 RAID bus controller: nVidia Corporation Device 0ad8 (rev a2) Subsystem: Micro-Star International Co., Ltd.

(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...
