https://bugzilla.kernel.org/show_bug.cgi?id=83201 Bug ID: 83201 Summary: CPU soft lockups in nouveau under load Product: Drivers Version: 2.5 Kernel Version: 3.17.0-rc1-00231-g7be141d Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: ted@xxxxxxxxxx Regression: No Created attachment 148071 --> https://bugzilla.kernel.org/attachment.cgi?id=148071&action=edit Full boot/run log I'm seeing a ton of CPU soft lockups in 3.17.0-rc1-00231-g7be141d when building a kernel (make -j8). It seems to lock up hard enough that I have to hard power off. Sorry if this is the wrong component. I guessed that this is a bug in nouveau. Full log attached.
