kernel panic docking laptop into dock with PS/2 keyboard/mouse attached
Last modified: 2015-01-04 17:22:56 EST
If I start my IBM ThinkPad T42 laptop undocked and then dock it into a dock that
has a PS/2 mouse and keyboard attached, it often kernel panics with messages like:
kernel panic - not syncing:arch/i386/kernel/semaphore.c:64:spin_is_locked on
uninitialized spinlock f0e359bc. (Not tainted)
The problem doesn't happen when I don't have a mouse and keyboard plugged into
the dock, nor does it seem to occur if I start up the machine docked and then
undock and redock it. It happens on both the current (2.6.13-1.1532_FC4) and
previous (2.6.13-1.1526_FC4) kernels.
This is a mass-update to all currently open kernel bugs.
A new kernel update has been released (Version: 2.6.15-1.1830_FC4)
based upon a new upstream kernel release.
Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.
This bug has been placed in NEEDINFO_REPORTER state.

If this bug is a problem preventing you from installing the
release this version is filed against, please see bug 169613.
I haven't been able to reproduce with the latest kernel, so resolving this bug
"worksforme." I'll reopen if I experience the problem again.
