Some problems and oddities I have seen:
UP, no preempt
* nfs gets stuck sometimes. klogd and rpciod shares the cpu,
umounting is impossible. cat'ing a nfs file shows the
contents but the cat process won't die. Stuck on close?
This also happens with 2.5.30
* ide-cd is broken as module
SMP, with and without preempt.
* During boot I get atkbd not present(ed), and the keyboard
is disabled. It wakes up later in the boot process, so
no big trouble here.
* raid has trouble, even with 4k maximum bio's.
The bootup e2fsck complains that it can't find a valid
superblock on my raid-1 and raid-0 devices, although
mount has no trouble. I get logged complaints about
e2fsck using outdated ioctl's for md. Strange that
fsck should needs to know about raid devices.
Possibly a problem with e2fsck 1.27?

Could you get me a log from tcpdump and 'echo 1 >/proc/sys/sunrpc/rpc_debug'
when this happens?

The warning about ioctl's is fairly bogus. It gets reported for *any*
unknown ioctl, whether it looks like it might be raid related or not.
So I wouldn't worry about that.
I have a new collection of patches for md which break if fairly
thoroughly. I am about to started testing/fixing and will
make sure that mkfs/fsck/mount work for raid{linear,0,1,5}.
