can you past the output of lsmod ?
this looks like the bug in the nvidia binary only driver; are you using that ?

sorry, i should have added:

no, i'm not using the nvidia driver.


however, i now notice that since i simply used netscape 4.77 insted of galeon to
try and create this bug, i have managed to create it and it seems to be working
ok.  i haven't started evolution yet either.  not sure if that's related or
not.  can it be?

It shouldn't be. Can you give a bit more information about this system ?
eg cpu type, memory etc

cpu: K6/2@500
vid: matrox millenium (x2, but this was happening before i added the second one)
mem: i actually have 4 configs i've been testing.  i have 2 128MB sticks and a
256MB stick.  normally, i have been running with one 128 and the 256, but i have
tried using only, trying both the 128 and the 256 separately.  still crashes in
a very similar manner.

I think I found a codebug; I'm building a new kernel with a patch and I hope
you're willing to test that to see if it fixes it.

you betcha i'm willing to try it.  all the sensitive data is being back up
hourly, just in case.  i'd HATE to have to reinstall an older version...

thanks!

Ok the i586 kernel is done, the i686 one is still building (there is a bit of a
queue in the buildsystem and I had to build on my workstation), the kernel is
versioned 2.4.3-18 and can be found at

http://people.redhat.com/arjanv/testkernels/

ok, new kernel installed and currently operating.  so far, it looks very good. 
i will keep y'all informed.

couple points:
1) is it ok that i'm using a K6/2 and this is an i586 kernel?

2) there was one case that seemed to trigger a crash somewhat regularly.  while
using galeon, if i tried resizing and/or scrolling while the page was still
loading, it seemed to crash the system more frequently.  just now, while loading
the bugquery page ( takes a nice relatively long time to load up and layout the
form ) i tried scrolling around.  i had galeon crash, but this time it just sat
with a unupdated window.  normally, when it crashes i get a little dialog box
popup, this was the very first time i've had it just stop updating.  SO, that
gives me a very good feeling about this update.

thank you so very much for your incredibly prompt and helpful attention to this
matter.  i promise i will report any thing i find as soon as it happens.

now, i'm off to try and get some work done!

hmm, had a similar crash this afternoon, i will attach the relevant log
separately.  when this happened, the machine was doing too much.  i had left it
for a little while.  when i came back, i had been dropped back to the gdm login
screen.

i am still convinced it seems better though.

let me know if there is anything else i can do.

/var/log/messages for latest crash(es)

after using my machine again for less than two hours, it once again crashed.  i
have attached the log from a crash on thursday before i took off for the
weekend, then the one from this evening.

i really do need to try and be able to actually work.  i'm seeing what i can do
about compiling the 2.2.19 kernel from kernel.org for myself to use, as well as
2.4.9 to see if that helps.

if there is still anyone working on this, i will still be willing to try new
kernels if need be, i just can't be having crashes every 2-6 hours, its just too
painful.
