so to test out the 2940 handling in 2.2.1, I boot up... ahc0 <Adaptec aic7880 Ultra SCSI host adapter> rev 0 int a irq 10 on pci0:12 ahc0: Using left over BIOS settings ahc0: aic7880 Wide Channel, SCSI Id=7, 16 SCBs ahc0 waiting for scsi devices to settle (ahc0:4:0): "WANGTEK 6130-HS 4G16" type 1 removable SCSI 2 st0(ahc0:4:0): Sequential-Access density code 0x13, drive empty probe0(ahc0:9:0): scsi_cmd probe0(ahc0:9:0): scsi_done (ahc0:9:0): command: 0,0,0,0,0,0-[0 bytes] probe0(ahc0:9:0): scsi_cmd probe0(ahc0:9:0): scsi_done (ahc0:9:0): command: 40,0,0,3,0,0,0,0,0,0-[0 bytes] probe0(ahc0:9:0): scsi_cmd probe0(ahc0:9:0): scsi_done (ahc0:9:0): command: 12,0,0,0,2c,0-[44 bytes] ------------------------------ 000: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 016: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 032: 00 00 00 00 00 00 00 00 00 00 00 00 ------------------------------ ... then try to dump a filesystem (dump 0bdsf 64 108000 9000 /dev/nrst0 /usr). Soon after, the tape drive hangs...and I see this: st0(ahc0:4:0): SCB 0x0 - timed out in dataout phase, SCSISIGI == 0x6 SEQADDR == 0x125 st0(ahc0:4:0): abort message in message buffer st0(ahc0:4:0): SCB 0x0 - timed out in dataout phase, SCSISIGI == 0x16 SEQADDR == 0x125 st0(ahc0:4:0): no longer in timeout ahc0: Issued Channel A Bus Reset. 1 SCBs aborted Clearing bus reset Clearing 'in-reset' flag , I kill the remaining dump program and try "mt status" only to be greeted with the following: st0(ahc0:4:0): SCB 0x0 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 SEQADDR == 0x6 st0(ahc0:4:0): SCB 0: Immediate reset. Flags = 0x1 st0(ahc0:4:0): no longer in timeout ahc0: Issued Channel A Bus Reset. 1 SCBs aborted Clearing bus reset Clearing 'in-reset' flag which seems to be repeating in some loop. 2.2.1-RELEASE FreeBSD 2.2.1-RELEASE #0: Tue Apr 1 23:47:31 EST 1997 (this is no APril 1 joke) Is there anyone interested in even trying to fix this ?
