I got hit with something that sounds very similar to this when upgrading to the 2.6.20-10-server kernel. My system works fine on -9. I ended up stuck in busybox with no mounted drives. I'm using a DG965 Intel motherboard with three SATA hard disks. The following are details on my RAID5 setup and LVM. My /boot partition is non-raid on the first SATA disk. What else do you need?
