My laptop (Lenovo Thinkpad T60) also suffers from this problem. I am running Gutsy and installed the 64-bit Hardy -rt kernel (2.6.24-16-rt). The Gutsy kernel works just fine for suspend resume for me. It seems that the Hardy -rt kernel has no problems suspending (all the fans go off, the suspended light comes on, backlight goes off, etc. It only seems to have problems on resume. The suspend light blinks off, the drives and fans spin up and the backlight comes on (with a blank screen). At this point, it just sits there apparently idle, yet not resumed. The keyboard does seem to have some effect -- caplock and numlock both make the appropriate lights light up on the keyboard. And sysrq keys work (well, at least sysrq+b reboots the computer).
I tried to capture some more output by connecting up to another machine and using a serial console. But I guess suspending does not write to the main console so that didn't capture any output. But it did seem to allow the computer to successfully suspend several times. Oddly enough, after booting without the serial console, it was back to hanging on resume again. The attachment contains the appropriate sections of /var/log/messages from a boot to suspend for a failed resume and the entire boot/suspend/resume cycle from a successful one. It also contains lspci -vvnn output. ** Attachment added: "tarball containing successful and failing messages and lspci -vvnn output" http://launchpadlibrarian.net/13567658/thinkpad-t60-logs.tar.gz -- linux-rt freezes on suspend https://bugs.launchpad.net/bugs/195018 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
