Subjectpre-patch-2.0.31-9 OOPSs
Someone mentioned that my old gcc (2.7.2) might be the cause of my OOPS's,
so today I compiled the kernel on a RedHat 4.2 machine with gcc 2.7.2.1,
and of course, I got a huge oops as soon as I started up trn. I'm running
inn 1.5.1-6 and trn locally. Inn is fed via rnews via uucp batch.

The first part here is pulled from the screen so I could run it
through ksymoops; the decoded OOPS's are from syslog. Let me know if
you want more/less raw output, or if these are even at all helpful.
The first oops may not be included in the first set from ksymoops,
since it scrolled off.

Meanwhile, my system has locked up when I wasnt home several times, so
I'd declare at least this patched version of 2.0.31 very unstable. I
will be going back to 2.0.30, which at least hasn't hung on me,
although I did get a few oops's from it. I don't know if unpatched
2.0.31 is any better or not.

This is from 2.0.31p9 plus several patches that Werner Fink suggested I try.

Output from ksymoops:
