I have these lockups on my Lenovo T520 as well. The system locks up completly but randomly. Nothing improved with the few sandybridge patches and the update to 2.6.38-10.
The only information I have, that this lockups occur running a compiz accelerated desktop. Additionally these problems occured more often while usage of java applications (like libreoffice or oracle sql developer). I am now testing whether using a metacity desktop improves anything. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/792849 Title: Lenovo ThinkPad T420 random hardlocks with Sandy Bridge graphics To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/792849/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
