[K8M890] ubuntu crashes after laptop unplug

[Fernando]

I was simply testing out the program "cheese" when I decided to go out into my living room. I unplugged my laptop and got ready to go when all of a sudden....Everything was black. I could see and move the mouse but that was all. I restarted the laptop and Ubuntu failed to boot for a while...It took me many tries before I got it to load up again(I was happy :D).

I just hope this does not happen again.

Hi Fernando,

So this has happened only the one time? Have you tried to reproduce at all? I do see the following in your CurrentDmesg.txt file:

[ 102.400352] powernow-k8: Hardware error - pending bit very stuck - no further pstate changes possible
[ 102.400359] powernow-k8: transition frequency failed
[ 102.540014] powernow-k8: failing targ, change pending bit set

I'd be curious to know if there are any other errors that may have been captured in /var/log/kern.log.0 after this happened.

I actually have it working now, it just took a while to boot after the
crash. I still am unable to unplug or plug the laptop in during the session.
It's either plugged in or it's not, if that changes the whole crash starts
over again(found out today).

The whole "powernow-k8" thing is normal to me...It happens all the time in
both computers I have Ubuntu installed on.

It will show that message while shutting down, logging off, but it never
affects the process of doing so. I Googled it one day out of aggravation and
wasn't able to get much out of it.

Oh yeah, I forgot to mention that I am running Ubuntu Karmic Koala(the
powernow error happened in 9.04 also).

Twice in two days I've unplugged and moved my laptop. Each time the screen went black, the on' button flashed steadily, and the laptop wouldn't respond to the keyboard. I used the 'on/off' button and restart was perfectly successful.

If you can from after reproducing this issue (or /var/log/Xorg.0.log.old).
