Hello,
I think I decoded this Oops correctly. The crash occurs before the
disk is mounted, so I am unable to access the contents of /proc/ksyms
and /proc/modules. However, the decoding using the modules and
System.map looks reasonable. Is the decoding accurate?
ksymoops -o /lib/modules/2.6.12-rc1-mm1/ -m
