The oops is not in yenta but most likely in the release() function of
fs/sysfs/bin.c and related to ipw firmware loading. The function is
touching already freed memory. As I am mostly clueless of sysfs and
hotplug, perhaps someone can give us a hint?
The oops from Zilvinas logs is the following:
Unable to handle kernel paging request at virtual address 6b6b6c6b
printing eip:
c0181cec
*pde = 00000000
Oops: 0002 [#1]
