Has anyone seen this oops?
Spotted on sparc32.

Phil.

ksymoops 2.4.5 on sparc 2.4.20-rc2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.20-rc2/ (default)
-m /boot/System.map-2.4.20-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.
