Actually, I do have them on the boxes which do not have the raid
controller. I have several boxes in hetzner. The ones that does not
have any additional devices attached to the motherboard seem like not
having the problem. However most of my machines have at least
additional NIC device.

Please note that my machines does not crash even when there is an
interrupt storm. On the other hand, they suffer from some performance
problems :/

The funny thing is that after reboot there's some silent period of
time, when the interrupts are OK. After the systems becomes to be
loaded more, the interrupt rate increases unless it reaches around
350k interrupt rate...

I have tried to play with the BIOS settings, nothing really helped.

I have tried to ask them to update the BIOS in the past, AFAIR they
replied that the BIOS update is up to me...
