Thanks for your replies.
I suspect here hibernate!
I don't know it very well, but I have problems after wake up from supsend or

I have installed 2.6.31 (custom) recently, but don't think this is the
reason.

After I reboot it looks normal, so may be you are correct. It's either some
script/hibernate or udev issue.

It's not that urgent to fix today, but would be nice to have a solution.
