Description Patrick 2007-02-16 18:17:09 EST
Description of problem:
Kernel oops, bluetooth mouse stops working. When shutting down, "stopping hidd"
hangs. (not sure if I am correct in blaming hidd from bluez-utils. Maybe it's a
kernel bug in which cause please correct).

Version-Release number of selected component (if applicable):
kernel-devel-2.6.20-1.2930.fc7.i686
bluez-utils-3.9-1.fc7.i386

How reproducible:
Wait for it to happen. Seen it happen twice with yum -y update. Have also seen
it happen several times when the blank screen + lock had kicked in and I enter
the password to unlock the screen

Steps to Reproduce:
1. start laptop
2. wait for it to happen
3. kernel oops
  
Actual results:
Kernel oops, bluetooth mouse stops working, stopping the hidd service when
shutting down hangs forever.

Expected results:
No kernel oops, working bluetooth mouse.

Comment 1 David Woodhouse 2007-02-18 05:26:36 EST
Sysfs b0rkage. I think this is what I've seen ever since we turned on
CONFIG_SYSFS_DEPRECATED in 2.6.19-1.2914.fc7
Comment 2 Patrick 2007-03-02 10:03:12 EST
The problem is still present in the 2.9.20-1.2960.fc7 kernel. The easiest way to
reproduce this  issue consistently is to the set screensaver mode to blank
screen+lock and let it kick in. Log in and check /var/log/messages for the info
about the kernel oops. The bluetooth mouse no longer works until I reboot.
Comment 3 Patrick 2007-03-02 10:49:39 EST
Seems you don't even need to have the screen lock when the screensaver kicks in.
Without the screen lock after the screensaver has kicked in the kernel oops
happens just as reliable :(  Hope this helps in tracking down the issue. If you
need more info please let me know.
Comment 4 Patrick 2007-03-13 10:29:56 EDT
The problem is still present with today's Rawhide and kernel 2.6.20-1.2985.fc7
