[RESUME 15.076s] slow resume after suspend to ram

[Heiko Scheit]

From the dmesg output it seems that there might be a problem with device MAT0019:00.
It failed to resume and it also seems to take a long time.

I should add the computer was booted directly from a Karmic CD.

Hi Heiko,

The warning reported here typically indicates that it took longer for your system to resume from suspend than expected. I believe there is a 5 sec barrier which your system likely exceeded. Based on your dmesg output I see PM: resume devices took 15.076 seconds. I'm setting this to traiged for further investigation. Thanks!

There is another problem, but only when the laptop runs on battery. There seems to be some time limit for entering the password after suspend. After that limit the laptop goes to sleep again.

So, due to the long time it takes to resume, I sometimes just see the login screen for 1-2 seconds before the laptop goes to sleep again. This is quite annoying, actually almost unacceptable. Imaging you have to give a presentation and all people see is that you laptop wakes up and goes to sleep again... So, maybe the importance of this bug should be increased.

I can also try to find out what the problem is, if you give me some hints where to start. It seems the problem is caused by ' Device MAT0019:00'. Do you know what this is? Maybe it is not needed and this can be skipped?

I may have reported a duplicate of this bug here:

At any rate, the overall form of the bug seems similar, even though the dmesg lines look different.

I should say that I previously had other lines surrounding my 20-second gap. I removed those modules, but that did not help at all. The gap remained, even though the adjacent lines were all different.
