: We tried to set the IRQ for your device and the BIOS choked. Can you get the
: output from /usr/src/tools/tools/pirtool for your machine?
Once upon a time, I encountered many BIOSes that would happily map the
first interrupt on an interrupt pin at the PIC. Further ones would
result in an error, so I made the code ignore errors all the time.
Looks like they are no longer ignored. I never found out if ignoring
the error was OK or not, since the documentation was a bit thin in
