Kernel update to 2.6.25.18-0.2-pae brakes suspend to ram
Last modified: 2008-11-02 11:42:05 UTC
This is OS 11.0 on a Thinkpad T61. Suspend to ram worked like a charm until the latest kernel update. I did install every kernel update just in time, so the previous version should be known by the developers. Now with 2.6.25.18-0.2-pae, the laptop wakes up, but there is only a blank display, no chance to get to a console with CTRL+ALT+F2 etc.. Any logs to give you?
I just tried to do a suspend to ram as being able to upload the kernel log, but now it works. Strange thing, as I had it failed three times yesterday. I'll reopen if it will occur in the future. Sorry for the noise.
So I got it to fail. There are two ways to wake up the laptop: 1. Do a suspend, do _not_ close the display, press the function key to wake it up. This works 100%. 2. Do a suspend, _do_ close the display, reopen the display to wake it up. Fails 100%, only chance found is a hard reset. This did work with the previous kernel version. I'll attach a log which includes a few successfull examples with method 1 and the last part which shows the failed one with method 2. The machine is a Thinkpad T61, with GM 965 and intel graphics, I think it's called GMA X3100.
Created attachment 249249 [details] /v/l/m with both successfull suspends and one failing
