The 950322-SNAP was released two days before I had my 48 hour spurt
of work on the driver. The one in -current is rock solid as far as
the controllers go... I'm down to fixing device quirks now. I would
suggest picking up the -current driver, but as a stopgap, this might
be enough to fix your problem:
/* Determine channel configuration and who we are on the scsi
bus. */
switch ( (sblkctl = inb(SBLKCTL + iobase) & 0x0f) ) {
case 0:
ahc->our_id = (inb(HA_SCSICONF + iobase) & HSCSIID);
printf("Single Channel, SCSI Id=%d, ", ahc->our_id);
+ outb(HA_FLAGS + iobase, SINGLE_BUS);
break;
And add this somewhere:
#define SINGLE_BUS 0
