Well, I got a hint in e-mail from Nir Mor to disable APIC from the BIOS.
I have been looking at the BIOS settings earlier, but they
didn't help. I had tried everything, except enabling the
IDE channels. I have had them disabled, as I don't have
any IDE drives, only SATA. Well, it solved the problem
for me. When I have *both* unused IDE channels enabled,
there are no lost interrupts, but even if I disable
one of them, I get lost interrupts.
Not looking at the code at all, I have no idea whether this is
a bug in the hardware or in the code - or in the BIOS user
interface - letting me disable "very important" devices :-)
