Red Hat Bugzilla – Bug 863038
Possibly serious kernel issue - Firmware bug
Last modified: 2012-11-01 20:19:13 EDT
Description of problem:
I have noticed lately as I receiving the new and newer kernels randomly my mice cursor and my implemented touchpad (synaptics one) totally freezing out, and inside the /var/log/message file contains huge amount of touchpad timeouts, and something else that I don't know how should I mean it. So, how can I handle this, and set apic to 500? My CPU is AMD MII-320, dual core. The error is:
"[Firmware Bug]: cpu 1, try to use APIC500 (LVT offset 0) for vector 0x400, but the register is already in use for vector 0xf9 on another cpu kernel: perf: IBS APIC setup failed on cpu #1"
Version-Release number of selected component (if applicable):
First after 3.4.6-2 has appeared, and I can't get rid of that bug. But I can still notice at current version 3.5.4-2.fc17.x86_64 #1 SMP
I don't know, it's just appears randomly (sometimes every minute, sometimes after hours), and renders to unusable the touchpad, and I can't do against it nothing, just full warm restart.
Steps to Reproduce:
see earlier point.
The system randomly producing this freeze out, that kills the integrated touchpad. When I plug a new hw, an external mouse in this frozen state, the cursor works again with the newly connected mouse, but the touchpad stays dead until full restart.
No such bug and effects.
I notice with that freeze overheating, and turns my laptop to a wild hairdryer as temp climbing up to 76 Celsius. So something is wrong, that hasn't been present earlier, and I would like to provide any of my log files that necessary, just tell me witch one you need.
does 3.6 improve this at all ?
Is there anything interesting in /var/log/Xorg.0.log about the touchpad ?
This has been changed with the last updates, no errors or timeouts for touchpad - however - kernel firmware bug message still exists. But No freeze since last updates.
