'deadline':

$ cat /sys/block/hda/queue/scheduler 
noop anticipatory [deadline] cfq

As others already reacted with data regarding this test I assume you
don't need my data anymore.

I understand this problem must be quite annoying for the Reiserfs team
as you can't reproduce it. In my case it also only happens on one
system, and not on another.

Maybe we can collect data? I'm happy to set up a page with 'good' and
'bad' configurations. Any suggestions as to what you need?

My 'good' system:
kernel:		2.6.15-rc1-mm2
OS:		Debian Sid
disks:		4x sata on Promise
raid/lvm/etc:	lmv stripe

My 'bad' system:
kernel:		2.6.15-rc1-mm1
OS:		Debian Sid
disks:		ata on nForce2
raid/lvm/etc:	none, single disk
