Description Dirk Kleinhesselink 2000-11-30 04:50:00 UTC

System is a Supermicro P6DGE dual processor P-II system with a USR PCI
modem.  FreeBSD 3.x ran great on this box in SMP mode, no problem.  PCI
modem showed up on sio2 using irq 5.  Modem works fine with the GENERIC
4.1 kernel, but does not work with kernel compiled for SMP:

boot message from GENERIC kernel:

/kernel.GENERIC: sio4: <U.S. Robotics 56K FAX INT> at port 0x3e8-0x3ef
irq 5 on isa0

boot message from SMP kernel:

/kernel: sio4: configured irq 2 not in bitmap of probed irqs 0
/kernel: sio4: <U.S. Robotics 56K FAX INT> at 0x3e8-0x3ef irq 2 on isa0

The only changes in the kernel config from GENERIC were the enabling of 
the 2 required lines for SMP.

How-To-Repeat: build a 4.1 kernel with SMP enabled.

Does this problem still occur with more recent releases?
