https://bugs.freedesktop.org/show_bug.cgi?id=33222 Summary: random hang-up with nouveau when browsing with Google chrome Product: xorg Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Driver/nouveau AssignedTo: nouveau at lists.freedesktop.org ReportedBy: zhangchi866 at gmail.com QAContact: xorg-team at lists.x.org Created an attachment (id=42141) --> (https://bugs.freedesktop.org/attachment.cgi?id=42141) Xorg's log file when the screen is locked up Machine: Acer AS4741G Laptop, GeForce GT330M OS: Ubuntu 10.10 with kernel 2.6.35-24-generic ppa kernel 2.6.37-12-generic Description: While nVidia's official driver does not work on this machine with Ubuntu 10.10 at all(kernel module crashes when Xorg starts), nouveau has been working quite well during the most of the time. However, my screen gets locked up sometimes, while the mouse can still move(I guess that's because of the KMS?). Eventually I noticed most of the hang-ups occur when I am browsing with Google Chrome. If I simply press SysRq + E, nothing interesting will happen. However, if I press Alt + F1 then Ctrl + Alt + Delete, I can get my terminal output back, with mouse pointer still on it(and still be able to move). When the system is rebooting, I noticed some interesting output generated by nouveau kernel module, unfortunately I failed to capture it. It was about freeing pipes or something like that. How to reproduce: Open Google Chrome and do some browsing. Sometimes it will occur.
