I'm trying to enable a generic ISA multiport SIO card in -current from
just before the signal changes and get presented with the above panic
when the first SIO port on the card is attached. Since it seemed to
be a problem with the resource allocation, I tried turning on
RMAN_DEBUG, but that just suggests that the problem is elsewhere.
The relevant part of my config is:
options COM_MULTIPORT
device sio0 at isa? disable port IO_COM1
device sio1 at isa? port IO_COM2 irq 9
device sio2 at isa? port IO_COM3 irq 3
device sio3 at isa? port 0x2e8 flags 0x605
device sio4 at isa? port 0x2f0 flags 0x605
device sio5 at isa? port 0x3e0 flags 0x605
device sio6 at isa? port 0x2e0 flags 0x605 irq 4
I originally set this up under 2.2.6 with sio3 as the master port,
and it worked (as long as sio0 was disabled). When it didn't work
under -current, I RTFM and noticed that the master port should be
the highest number, but that didn't help.
The relevant part of the boot response is:
