Update: removing the ATI display driver and my machine suspends and resumes happily. This implies its a bug in the ATI closed source display driver -not something that anyone else can fix.
I tried the debugging kernel suspend/resume tricks, but no crash report gets generated. Is there any way to force some stack trace during a suspend or otherwise debug a display driver that is hanging on suspend? Alternatively, how could we improve the OS so that if a driver doesn't suspend properly, that failure is detected and acted on, rather than leaving the laptop to stay live and overheating as it is transported? I can possibly see how to do failure detection , but acting on the failure, that's tricky. -- Suspend/hibernate/resume failure in Ubuntu 10.04 64-bit on HP Pavilion dv4t-1000 https://bugs.launchpad.net/bugs/605133 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
