Hi,
If Linux detects an inconsistent pirq table, it will refuse to use it.
The attached patch fixes the pirq table in case LinuxBIOS finds a
problem.
Since there was kind of a common sense that pirq tables et al should be
generated by LinuxBIOS instead of coping with hard codes, this might be
a first but very small step.
If I get no objections, I'd like to check it into the freebios2 cvs
soon.
Stefan
