Not Sparc64, but i686, but a heavy Oops on 2.6.1

Fedora kernel-2.6.1-1.65 (basically a 2.6.2-rc2-bk4)
Have had Oopses with all 2.6.1 up until now, but have not been able to capture
one, as the system locks up hard before anything is written to disk.

Now it just oopses, the module is loaded (and is visible in `lsmod`).
However, the module can not be unloaded - rmmod complains that the module is in use.

i[f|w]config shows no devices.
