Karmic RC fails to suspend (freezes) on Thinkpad X61s

[Kaaahn!]

1) Ubuntu 9.10, kernel 2.6.31-14-generic
2) not sure what package this affects
3) I expected my computer to suspend properly: the suspend light comes on solid, and the screen turns off, etc.
4) The suspend light is flashing, the screen is still on showing the desktop, but the system is frozen.

Karmic release candidate fails to suspend properly on my Thinkpad X61s. The suspend light does not stop flashing and my screen does not turn off. The system freezes and is unresponsive, and I need to hold the power button to turn it off and back on again. It boots up normally into a new session.

This does not appear to be the same as other suspend bugs being reported where they cannot resume from suspend. In my case, I don't appear to be suspending at all.

I have attached my pm-suspend.log

The same thing happens on my Lenovo T61. Observations and experiments showed that suspend works before I log in to the system, from that point suspend doesn't work and it hangs the way described above.

Installed BETA and keeping up to date system through available updates... Ubuntu 9.10, kernel 2.6.31-14-generic

[Kaaahn! (cnetrix)]

I tried that and you're right-- while I'm on the gdm login screen I can successfully suspend and resume the machine. It's only once I get into a session that I can't suspend properly.

It did suspend before, when I installed from Alpha 4.

What's interesting is that today I tried to suspend from Fedora 12 beta on the same machine and it gives me the same response... frozen. Perhaps it's a problem in the 2.6.31 kernel? Or something else that's common to the two distros that has to do with suspending...

I have the same problem on my Thinkpad X40. I haven't tried to suspend without logging in. But logging out to GDM and suspend doesn't work. neither does suspend from GNOME.

The only different from a clean install of ubuntu 9.10 is that I have installed pulseaudio package.

As it was said in the Bug #464712 a suspend freeze can be caused by a mounted SD card. When the card was removed (tested on my machine) or unmounted the system can suspend and above described behavior is no more present.

[Kaaahn! (cnetrix)]

That appears to be it exactly! I have an SD card that I leave in the slot and use as extra storage. When I suspend with the SD card mounted, it freezes. However when I unmount the SD card it suspends normally.

[Tesuki (tesuki-deactivatedaccount)]

I had a SD card mounted as well. I removed it and then suspend work.
On the other hand resume dosn't work. When it resume backlight wont come on (probably another bug).

[Peter Harding (phh-hardnet)]

This a seems to only happen with my 8GB SDHC card mounted and not my 2GB SD card in both my Acer Aspire One 110 and my Dell Mini 9 (8GB SSD). The regular SD card suspends and resumes normally.

[Matt (proxver)]

Same problem, Lenovo T61 laptop, had a 4GB flash card in. However, this issue was not present in 9.04.

[Andy Walker (number-man-2000)]

This doesn't matter if I have a SD card or not inserted, the X61s fails to suspend or hibernate and simply panics.

Also, power management is inoperative, too. There is no auto-adjustment of screen brightness, etc. and I can't even change it on the fly.

I'm using Kubuntu Karmic w/ all latest updates

I do not believe this bug is a duplicate of #464712 . I have an X61s (and don't use an SD card) and am having the same symptoms as comment #10 by Andy Walker. Let me know if I can help with logs or anything.

[Andrew (andrewlevine)]

Looked into my problem and responding here for others benefit. My problem was that I was using an Intel graphics PPA and when I upgraded to Karmic my Intel video driver was held back. When I deleted the PPA and reinstalled xserver-xorg-video-intel all problems were fixed and there was a noticeable improvement in hardware acceleration as well. Thanks all for your work

I don't think it's a duplicate of bug #464712. I don't have a mounted SD card but the problem also occurs. (But not always.)
