Hi Fabio, Are you able to reproduce this freeze with current oneiric?
If so, please collect a mmiotrace on the bug. $ mount -t debugfs debugfs /sys/kernel/debug $ echo mmiotrace > /sys/kernel/debug/tracing/current_tracer $ cat /sys/kernel/debug/tracing/trace_pipe > mydump.txt & Start X or whatever. $ echo "X is up" > /sys/kernel/debug/tracing/trace_marker $ echo nop > /sys/kernel/debug/tracing/current_tracer Check for lost events. For more help on using mmiotrace, see http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/trace/mmiotrace.txt ** Changed in: xserver-xorg-video-nouveau (Ubuntu) Status: New => Incomplete ** Summary changed: - Edubuntu amd64 20110619, xorg infinite loop + GPU lockup on Edubuntu amd64 20110619 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/799412 Title: GPU lockup on Edubuntu amd64 20110619 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/799412/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
