I too have had this problem with the 2.3.99pre3 and pre5 kernels.
Single Processor, Cryix 200.
Kernel compilied with std set of options, and Magic SysReq.
The only way I was able to figure out what process had caused
the problem was Magic SysReq + t (dump list of tasks).
ps xa hung. Infact all attempts to go into /proc/<pidofhungprocess>/
hung.
A very strange and annoying problem. I was able to kill the ps processes
that had hung with SysReq + k (SAK).
I unfortunatly don't have the time to try to debug and find what is causing
the problem, and I'm not able to repeat the problem either. :/
Although, NFS could well be a contributing factor.
