Apparently, mount does not work with partitions located on a 3ware RAID (8006-2PL controller) in a dual-Opteron box (64-bit kernel). If the kernel is configured with preemption and NUMA, it cannot mount any "real" filesystems and the output of "mount" is the following: rootfs on / type ext3 (rw) /dev/root on / type ext3 (rw) proc on /proc type proc (rw,nodiratime) sysfs on /sys type sysfs (rw) tmpfs on /dev/shm type tmpfs (rw) (hand-copied from the screen). I have tried some other combinations (ie. preemption w/o NUMA, NUMA w/o preemption etc.) and it seems that it works better with CONFIG_PREEMPT_NONE set, although even it this case some filesystems are mounted read-only. The mainline kernels (ie. -rc3 and -rc3-git[1-4]) have no such problems.
