Lock Ups During Shutdowns/Restarts

[uRock]

I am having problems on two of my machines with them locking up during shutdowns and restarts, which force me to do a hard power off. One system is running 11.10 and the other is running 12.04. Both are 64 bit CPUs with 64 bit ubuntu. The following output is from the 12.04 machine,

00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09)

Please help me with this issue.

Just wondering how this works hit ctrl+alt+f1 login to the console and type
sudo shutdown -h now

and see if that locks it up.

or sudo shutdown -r now
to reboot

sudo halt caused a lock, while the two shutdown commands worked fine.

This problem is usually intermittent. It only happens once every few attempts.

I'm just wondering are you using a Nvidia card? I had a very similar problem when I was using a Geforce 6150se Nforce 430 when I updated the driver to 304 from x-swat it cleared up most of the problems I was having with the regressed IMO Nvidia 29x drivers.

I have a Radeon HD 6450 card. Both systems having problems have ATI cards.

I have tried the advice here, http://askubuntu.com/questions/13214...t-and-shutdown which failed.

hmm I know the x-swat has the latest drivers for ATI cards as well might be worth a shot to upgrade those to there latest drivers.

It worked great when I was using a Geforce card I don't know about ATI but it's worth a shot oh and install ppa-purge to just in case it really messes up your system you can purge it and revert back to what you have now.

Thanks for the advice. Are the drivers offered in this PPA newer than the ubuntu repo versions. I really want to be able to put this behind me and get my ubuntu running right without having to do hard shutdowns.

Cheers and Blue Moons,

I installed the repo. It upgraded a xorg package, but the problem is still there.

I installed the latest driver from ATI.com. Hopefully this fixes the problem.

Will mark as solved once I hit a decent number of restarts without any issues.

Number of problem free restarts/shutdowns: 13

I am pleased to say the problem has not recurred.
