Hello Thomas.
I recall myself having had similar problems during heavy disk I/O (UFS 
and ZFS) with stuck console, stuck clients and especially stuck 
X11-clients. The discussion was really 'hot', but in the end no clear 
statement was made whether this is disk-i/o related or a deeper problem 
in the scheduler.

Sorry for the lack of the link, I thought Phoronix is well known ...
