Subject2.4.21-pre3-ac4 oops in kmem_cache_destroy
I have problems with the stability of my 2.4.21-pre3-ac4 machine.

It's a dual tualatin, with registered ecc DDR memory. After the oops,
the machine hangs hard. Very hard. So I've written it down by hand - and
hope I didn't make a mistake somewhere. Can anybody shed some light on
this?

Thanks,
Jurriaan

The decoded oops looks like this:

ksymoops 2.4.8 on i686 2.4.21-pre3-ac4. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.21-pre3-ac4/ (default)
-m /boot/System.map-2.4.21-pre3-ac4 (default)

Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

Error (regular_file): read_system_map stat /boot/System.map-2.4.21-pre3-ac4 failed

I know, the vmware modules are loaded. It's unstable without them also,
it just took me a while to be convinced to write the oops down by hand
:-)
