With 2.6.35-24.42: Following https://wiki.ubuntu.com/DebuggingKernelSuspend (i.e. echo 1 > /sys/power/pm_trace), the CMOS time doesn't seem to be reset to a debug value upon boot after hang/power-cycle (the time is still exactly correct), so I think any "hash matches" message is invalid. I think reading that page, pm_trace only debugs failures resuming from a successful suspend, not issues actually suspending?
Following https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume (i.e. booting with no_console_suspend, and suspending from text mode using pm-suspend), the symptoms of the hang are identical, and I don't see any kernel log spew from the hang. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/695249 Title: ASUS G73JW fails to suspend or hibernate: "pm_op(): usb_dev_suspend+0x0/0x20 returns -2" -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
