Hi All, I've recently upgraded my 3.4-STABLE box to 4.0-STABLE. The upgrade went fine, except something seems to have gone awry with my SCSI set-up... The machine has 3 x 2940's in it, and one 1542 (not actually used for anything yet). Under 3.4 the system would boot, and run fine... I've got data on most the SCSI drives, I used to backup my NT workstation to them across a 100Mb/FDX link and get good performance (~4-5Mb/sec), and no errors... I'm very sure all the drives etc. are terminated OK - after having spent a lot of money getting decent cables, active termination etc. If I boot a 4.0-STABLE kernel, I get heaps of: " Waiting 4 seconds for SCSI devices to settle de0: enabling 10baseT port (probe15:ahc1:0:0:0): SCB 0xe - timed out in Message-in phase, SEQADDR == 0x157 (probe15:ahc1:0:0:0): Other SCB Timeout (probe16:ahc1:0:1:0): SCB 0xd - timed out in Message-in phase, SEQADDR == 0x157 (probe16:ahc1:0:1:0): BDR message in message buffer (probe16:ahc1:0:1:0): SCB 0xd - timed out in Message-in phase, SEQADDR == 0x157 (probe16:ahc1:0:1:0): no longer in timeout, status = 34b ahc1: Issued Channel A Bus Reset. 15 SCBs aborted Timedout SCB handled by another timeout (probe18:ahc1:0:3:0): SCB 0xd - timed out while idle, SEQADDR == 0xa (probe18:ahc1:0:3:0): Queuing a BDR SCB (probe18:ahc1:0:3:0): no longer in timeout, status = 35b Timedout SCB handled by another timeout (probe15:ahc1:0:0:0): SCB 0xc - timed out while idle, SEQADDR == 0x4a (probe15:ahc1:0:0:0): SCB 12: Immediate reset.

I've left it for 1/2 an hour before "on the offchance" it would get past all the timeouts, and at least continue with no SCSI drives / missing drives, but it doesn't. I use a 'wired-down' SCSI config (included below), dmesg under 4.0-STABLE shows all the Adaptecs being found OK, " ahc0: <Adaptec 2940 Ultra SCSI adapter> port 0xe400-0xe4ff mem 0xffafd000-0xffafdfff irq 17 at device 18.0 on pci0 ahc0: aic7880 Wide Channel A, SCSI Id=7, 16/255 SCBs ahc1: <Adaptec 2940 Ultra SCSI adapter> port 0xe800-0xe8ff mem 0xffafe000-0xffafefff irq 16 at device 19.0 on pci0 ahc1: aic7880 Wide Channel A, SCSI Id=7, 16/255 SCBs ahc2: <Adaptec 2940 Ultra SCSI adapter> port 0xec00-0xecff mem 0xffaff000-0xffafffff irq 19 at device 20.0 on pci0 ahc2: aic7880 Wide Channel A, SCSI Id=7, 16/255 SCBs " This happens in SMP or non-SMP mode...

They worked fine under 3.4, I'd expect them to under 4.0 as well :) The kernel config I use to wire down the above is: " device ahc device ahc0 device ahc1 device ahc2 device scbus0 at ahc0 device scbus1 at ahc1 device scbus2 at ahc2 device da0 at scbus0 target 0 device da1 at scbus0 target 1 device da2 at scbus0 target 2 device da3 at scbus0 target 3 device da4 at scbus0 target 5 device da5 at scbus0 target 6 device da6 at scbus1 target 0 device da7 at scbus1 target 1 device da8 at scbus2 target 0 device da9 at scbus2 target 1 " Any help / info or suggestions gratefully received, as it is - I can only use the machine with the IDE's (under the new 'ad' drivers) - but these work fine, as did the SCSI once :) Regards, Karl Pielorz To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
