The cause has been found. The timer of that machine is seriously
broken, 1 second is approximately 500ms long.
It is a HP DL360 G4 and I configured the kernel without ACPI or
similar. Maybe there are some strange BIOS power management schemes
active. I will look deeper into the problem and report back.
A broken timer is _very_ strange to me (I didn't encounter that in the
last 12 years w/ custom kernels).
Cheers,
M.
