Hello
I'm running FreeBSD 3.1 and whenever my workstation reboots I get the
message :
(da0:ncr0:0:0:0): tagged openings now 15
What does it mean ?
I must say that I encounter scsi problems with this host but I can't
find where they're coming from.
Generally the machine freezes with messages saying ncr1 is on timeout.
For example :
ncr1:5: ERROR (0:91) (9-ae-800) (8/13) @ (script 6dc:190001cb).
ncr1: script cmd = 89030000
ncr1: regdump: da 10 80 13 47 08 05 1f 03 09 85 ae 80 00 06 00.
ncr1: have to clear fifos.
ncr1: restart (fatal error).
(sa0:ncr1:0:5:0): COMMAND FAILED (9 ff) @0xf0af9200.
ncr1: timeout nccb=0xf0c79600 (skip)
ncr1: timeout nccb=0xf0c79800 (skip)
ncr1: timeout nccb=0xf0c79a00 (skip)
Another one :
ncr1:4:ERROR (81:0) (f-aa-0) (0/3) @ (script 3f0: 48000000)
ncr1: script cmd = 7210000
ncr1: regdump: da 10 00 03 47 00 04 1f ff 0f 06 aa 80 00 0a 00
ncr1: target 4 doesn't release the bus
ncr1:4: ERROR (0:41) (f-aa-00) (0/3) @ (script 3f0: 48000000)
ncr1: script smd = 72100000
ncr1: regdump: da 10 00 03 47 00 04 1f ff 0f 06 aa 80 00 0a 00

The precise configuration is 2 Tekram 390F cards + 2 towers of disks
(4 disks each, IBM 9.1 Go), one DLT and one QUANTUM for the system :
ncr0: <ncr 53c875 fast20 wide scsi> rev 0x26 int a irq 9 on pci0.9.0
ncr1: <ncr 53c875 fast20 wide scsi> rev 0x26 int a irq 12 on pci0.10.0
...

The DLT is daisy chained with one UW tower and I don't use the narrow
connector on the tekram 390F. If I do so, the workstation just freezes
during the boot with an error like :
ncr1:5: ERROR (0:91) (9-ae-800) (8/13) @ (script 6dc:190001cb).
ncr1: script cmd = 89030000
ncr1: regdump: da 10 80 13 47 08 05 1f 03 09 85 ae 80 00 06 00.
ncr1: have to clear fifos.
ncr1: restart (fatal error).
(sa0:ncr1:0:5:0): COMMAND FAILED (9 ff) @0xf0af9200.
ncr1: timeout nccb=0xf0c79600 (skip)
ncr1: timeout nccb=0xf0c79800 (skip)
ncr1: timeout nccb=0xf0c79a00 (skip)
I must say too that I had the same problems with the same PC in
another configuration : the DLT was the same, the system disk was the
same, all other disks were different and not UW, the scsi cards were
NCR 810.
The scsi bus goinf timeout is always the one with the DLT.
Might it be faulty ?
