suspend/hibernate fails on MSI Wind U100 in karmic

[Sanne Wouda]

I'm trying to suspend the MSI Wind U100 with karmic (kernel 2.6.31-5-generic, devicekit-power 010-0ubuntu1). When I start suspend with `sudo pm-suspend`, the screen turns black followed by some hard disk activity, then the hard drive spins down.

Immediately after that, the disk spins up and I get a gnome-screensaver password prompt.

Not sure what is causing this, filing against devicekit-power, but it could be a kernel bug.

A few log files are attached (dmesg, pm-suspend.log), but I'd be happy to supply any information to diagnose this problem.

Thanks for your consideration.

This is fixed now for me. Still not sure what was causing this... Closing.

I'm reopening this bug again. My Wind stopped suspending after a reboot. This is what I see in dmesg:

I tried it with 2.6.31-9 and it does not work, too, but the screensaver login does not appear. It only starts to search for the WLAN.

I tried it with 2.6.31-8 and it works!

Also for some other MSI Wind U100 problems like no Bluetooth or SD Card support 2.6.31-8 helps.

Try disabling the webcam by blacklisting the uvcvideo driver. Something like:

$ sudo sh -c "echo blacklist uvcvideo > /etc/modprobe.d/local.conf"

Reboot and check uvcvideo is not loaded:

$ lsmod | grep uvcvideo

Try your SD reader, suspend, etc. If all that works, mark this bug as duplicate of Bug #435352.

Hope it helps.

Blacklisting ubcvideo fixed my suspend problems. I have no way to test my SD reader, but I'm assuming it works. Marking as a duplicate of #435352.

Thanks for your help.
