Oops with kernel 2.4.5 on heavy disk traffic - reproduce

I have reported before a kernel oops.

I now oberserved the same oops, with the same stack trace, and a Dell Poweredge 1550 with dual CPU, 1 gb RAM, only one disk and with little disk usage (most file activity via NFS, where this system is a client).

The kernel is identical to the one reported before, and the stack trace is identical too.

The oops occurred with the process 'top'

I have not yet found a way to reproduce the crash in a systematic way, I am running the kernel now on 4 different machines under heavy load, and will try to reproduce.
