2.4.17-rc2 oops

2.4.17-rc2 oops

[Sebastian Wenleder]

Hi!

I received this oops after approx. 4 days uptime...
gcc --version = 2.95.3

-
ksymoops 2.4.1 on i686 2.4.17-rc2.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.17-rc2/ (default)
     -m /boot/System.map-2.4.17-rc2 (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.

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?

Sebastian,

This looks like memory corruption of some kind...

Could you please run memtest86 on the box? 

Thanks

support or mailing list for CML2?

[rpjday]

  where's the proper forum to discuss CML2?  i just added
the latest version to the 2.4.17 kernel, started it and
am getting "bad token" messages almost immediately.
