Not necessarily. But you could be lucky. If we know that you are
triggering a genuine bug (not faulty hardware or NVidia driver) in a
Release Candidate kernel, you might get some more attention on the list.
If you manage to reproduce the bug with 2.4.21-rc2, please change the
subject to reflect that.

Did I understand you correctly that the crashes also happen when the
module is not loaded at all? (Even loading a module once can wreak
havoc, even if you remove it subsequently.) If so, could you please post
another Oops of an untainted kernel? (Most developers here will simply
ignore Oopsen with a tainted kernel.)

Do the crashes happen when the machine has high load or when it's idle
or are they not related to load at all? Does it happen more often at
night, when your room is hot, when somebody starts the washing machine,
etc... Do you see any pattern at all?
Depending on the pattern, we might be able to make an educated guess
what the problem is. Don't laugh, I've fixed quite a few bugs once the
pattern was clear (most of them hardware related, though).

Could you please enable all debugging options in the "Kernel hacking"
menu? The machine may run slower, but if it helps us getting your
problem fixed, it is worth it. Enabling software watchdog might also
help, but I'm not so sure about that.
