Anothor couriosity:
changing these lines in the kernel config makes the kernel freezing after
showing up the state of the amrd0: RAID array.
The 'sometimes' running kernel has option enabled:
options AUTO_EOI_1
options PQ_CACHESIZE=256
options HZ=1000
I disabled these options, because I thought maybe they cause some problems.
Now the running kernel doesn't start anymore :-)
Is this really a power supply problem? I think not.
