Strangely enough, here firewire controller is on the separate line
(this is rare).

Interrupt 18 (with yenta) is very busy, but seems it does not cause
any problems.
The main problem is ACPI.
When it works behind the scenes, it causes jackd to click:
delay of 2202.000 usecs exceeds estimated spare time of 1320.000; restart ...

The only way to workaround this is to boot with acpi=off. The thing
becomes stable as a rock, but looses battery/frequency/temperature
control. Which is a pity.

Dmitry.
