Now I followed https://wiki.ubuntu.com/DebuggingKernelSuspend because https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume gave nothing useful. I think the important lines from "dmesg" are:
>> First suspend and resume (successful) [ 4.889816] Magic number: 1:835:174 [ 4.889870] acpi device:0a: hash matches
>> Second suspend (suspend fails, have to restart computer) [ 4.889812] Magic number: 0:81:349 [ 4.889814] hash matches /build/buildd/linux-2.6.28/drivers/base/power/main.c:390
I attached both dmesg outputs.
