=======================================================================
As I don't have Sebastian's email address, I'm posting here.
I had a very similar problem after an openSUSE upgrade on an Acer
1501LCe laptop. At first I could not boot from the DVD, but a CD would
and compiling kernels had to be done in "powersave -l". It progressively
got worse and I was about to throw it out.
I decided to open it up a second time and have another look.
The outlet next to the CPU was blocked by an accumulation of dust which
I mistook for a foam filter the first time around.
It also seemed to be after a kernel upgrade - debated as such on the
openSUSE factory list.
I'm glad I did as it's fully back to health.
Regards
Sid.
