This system has been running 2.1.0-RELEASE just fine since it came out. However, when I try to boot the 2.1.5-RELEASE boot floppy, it PANICs every time, right after probing all the devices: panic: ahc0: brkintadr, illegal host access at seqaddr = 0x0 I've seen one other message recently regarding this same panic using an Adaptec 2742W on the "questions" list, but never saw any resolution. One possibility is that the default port numbers have changed. Compare this 2.1.5-RELEASE message to the 2.1.0-RELEASE message below. If this is indeed the problem, how do I get around it? ahc0: 0x5c00-0x5cff irq 11 on eisa0 slot 5 ahc0: aic7770 >= Rev E, Twin Channel, A SCSI id=7, B SCSI id=7. Any clues would be greatly appreciated. System dmesg output follows...
