Public bug reported: When unloading the nouveau driver using modprobe, a kernel oops is triggered. This is caused by a null pointer dereference in the wmi module which is unloaded when using modprobe -r nouveau. This bug was introduced in Oneiric, Ubuntu Natty does not suffer from this issue.
It's fixed in this commit: http://git.kernel.org/?p=linux/kernel/git/next/linux-next-history.git;a=commitdiff;h=023b9565972a4a5e0f01b9aa32680af6e9b5c388 Tested with the Makefile from http://pastebin.com/qmh3hPR1 $ uname -a Linux ubuntu 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux ** Affects: linux Importance: Unknown Status: Unknown ** Affects: linux (Ubuntu) Importance: Undecided Status: Confirmed ** Affects: linux (Fedora) Importance: Unknown Status: Unknown ** Tags: oneiric patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/885243 Title: "BUG: unable to handle kernel NULL pointer dereference" when unloading wmi To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/885243/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
