Kernel Oops when de-registering USB
From: sven
Date: Sat Nov 15 2003 - 14:56:26 EST
Hello,
first of all: sorry for sending to this address, I'm not sure where
the problem really is.
Description:
With the gentoo development-sources 2.6.0-test9 kernel I sometimes,
but not always get a kernel oops when shutting down.
System information:
This is a Intel D865PERLK mainboard with its on-board USB hub(s),
connected to it is a Lian Li USB 2.0 card reader (i.e. I got the oops
with only that connected).
Here are the files/outputs:
