2.4.2-ac23 nfsroot on a 386SX/20 with 6Mb RAM

On boot to single user, 'ls' and 'ls -l' work fine.

After mounting /proc, 'ls' still works, but 'ls -l' fails
with SIGILL after reading /etc/timezone (so says strace).

Unmounting /proc fixes the problem. Unmounting /dev doesn't.

I also, just now, had a spate of 'permission denied' errors
while trying to ls /dev/ subdirectories, and unexpected stale NFS handles.

The problems are varied enough that I suspect bad hardware, but would
flaky RAM cause such similar failures repeatedly? And is there a way
to test RAM explicitly?

Any tips appreciated, either to me (ebuddington@wesleyan.edu) or to
the list.

-Eric
