I have found an issue that triggers by running lsof. The problem is

looks like it could be a race condition or the file pointer is being
corrupted. Any pointers on how to track this down? What additional
information can I provide?
Hi,
2 things in general:
a) Can you test with a more recent kernel?
b) Can you reproduce this without loading the proprietary &
out-of-tree
kernel modules? They should never have been loaded after bootup.
I.e., don't just unload them -- that could leave something bad behind.
Heh, the EIP contains part of the name of one of the modules:
[ 8057.297159] BUG: unable to handle page fault for address: 31376f63
^^^^^^^^
[ 8057.297219] Modules linked in: ITXico7100Module(O)
^^^^
Perhaps this is a dumb question, but how could this happen?
