Description of problem:
On most newer HP notebooks, Bios gets into a "Bad State" when shutting down or
rebooting Linux without removing psmouse module beforehand (which is
apparently impossible in Fedora Core). In the Kernel-Bugzilla there are
patches for this issue which are in the upstream of 2.6.21
(http://bugzilla.kernel.org/show_bug.cgi?id=5534#c204). I suggest adding them
to the 2.6.19 Fedora-kernel-packages as novell did the same for suse and they
didn't experienced problems.
Shutdown or reboot
Bad State of the Bios causes several errors depending on which hp notebook one
acpi-events and battery-status are not getting updated anymore
fans are not working properly
cpufrequency is not set properly
Apparently will be fixed in 188.8.131.52
Should be fixed in kernel-2.6.19-1.2911.6.5
I can confirm it working with 2.6.19-2911.6.5. Bios not in Bad state anymore
on HP Compaq nx6325.
However there are still problems updating Battery and AC status.
Please test 2.6.20-1.2925.fc6
Does not work unfortunately :-(
still the same problem
