Bug#658778: Suspend from X session hangs Asus laptop.

Removing only ehci_hcd, hibernation works perfectly. If only xhci_hcd is removed, the screen is blanked but stays on. A power cycle is necessary, although the computer then resumes OK. Nicely done.

Bug#658778: Suspend from X session hangs Asus laptop.
Thanks for the quick reply, Jonathan. Is this a regression? Not really (the machine is new). I tried older debian 5.09 and 6.03 live cds. With 6.03 suspending from a session worked under some conditions (lid) but not all (menu). Does suspend-to-disk (triggered with echo disk /sys/power/state This doesn't work. ) work? If you have time to follow the instructions from basic-pm-debugging.txt[1] to narrow down the cause, that would be very useful. Thanks for the pointer! For some reason I didn't find it while searching around (we beginners don't know to search for pm- instead of suspend). Maybe a link could be added on the debian wiki at http://wiki.debian.org/Suspend ? The shutdown method described in the document seems to work. But it is a bit clunky and it wasn't immediately obvious how to set this option permanently or whether it even applies to suspend to RAM (more for the wiki...) In the meantime I found the following site http://thecodecentral.com/2011/01/18/fix-ubuntu-10-10-suspendhibernate-not- working-bug and shamelessly copy-pasted the suggested script. It works pretty well - the only obvious problem at the moment is that waking from sleep requires a press of the power button (lid-opening doesn't suffice). But at least there is no freeze with data loss and reboot. Huge progress. The working shutdown method suggests a bios issue and the copied script indicates a usb problem. Follow up might therefore look at the usb settings in the bios and investigate a bios upgrade (the changelog mumbles something about usb). The comments on the web site suggest that the solution has helped a lot of people and with different machines.

Hi again, Boris Barbour wrote: The shutdown method described in the document seems to work. But it is a bit clunky All right --- that's useful to know. Of course I was not suggesting this as a workaround but as a diagnostic tool. [...] In the meantime I found the following site http://thecodecentral.com/2011/01/18/fix-ubuntu-10-10-suspendhibernate-not-working-bug and shamelessly copy-pasted the suggested script. It works pretty well Can you reproduce this result without that script? Like so: modprobe -r ehci_hcd modprobe -r xhci_hcd echo disk /sys/power/state modprobe ehci_hcd modprobe xhci_hcd If so, could you also try unloading/loading only one of the two drivers to see which one is the culprit? Please attach acpidump output (so we can learn about the BIOS) and full dmesg output from booting and successfully hibernating/resuming in the platform mode with USB drivers unloaded (which will tell us many things).
