Hello, Why is BUS_BUFFER = 16 ? What does it mean exaclty ? I'm asking because I compiled an mpacpi kernel and I had to increase it to 128 because of: pci1 at pchb1 bus 128panic: Increase BUS_BUFFER in mpacpi.c! Stopped in pid 0.1 (swapper) at netbsd:cpu_Debugger+0x4: leave db{0}> Thanks, Mihai P.S. please CC answers to me
