Subject2.0.39 oopses in sys_new(l)stat
I wonder if there might still be a bug in 2.0.39 sys_new(l)stat. Today, one
of my trustworthy servers crashed (see details below), and it has actually
given me two slightly similar looking oopses before.

While this might be a hardware problem (I'll run memory test asap), it seems
that the oopses are quite similar and could perhaps be caused by a kernel
bug.

This is vanilla 2.0.39 (2.0.37 before), gcc-2.7.2.3, Ppro-200, Intel
motherboard etc. It has been very reliable in past. These oopses are the
_only_ problems. It runs qmail, samba, cvs, rsync, apache, pop, sshd and
oracle. All local fs's are plain ext2.

I hope somebody (with more kernel hacking experience than me) is still
interested in the 2.0.39. I'll be happy to provide any additional details or
try something. The oops will propably be hard to reproduce, however.
