Subject: Rev 1.147 of cam_xpt.c kills me
Hi,
I have an internal IDE to U2W SCSI RAID subsystem with 5 IDE-Disks in RAID5
which hangs on an Adaptec 2940.
All is with an 4G, 3200+, ASUS A8V-deluxe.
With your above patch a new kernel hangs after finding a da1 on LUN
32. (Seems that da1 is the same device as da0).
Then I get bus resets and broken SCB's...
I can reboot but have to power down the system to get the RAID subsystem
working again.
Dmesg with Rev. 1.146 of cam_xpt.c:
...
ahc0: <Adaptec 2940 Ultra2 SCSI adapter (OEM)> port 0xb000-0xb0ff
mem 0xfad00000-0xfad00fff irq 19 at device 14.0 on pci0
ahc0: [GIANT-LOCKED]
aic7890/91: Ultra2 Wide Channel A, SCSI Id=7, 32/253 SCBs:
...
da0 at ahc0 bus 0 target 0 lun 0
da0: <easyRAID Volume Set # 00 R001> Fixed Direct Access SCSI-3 device
da0: 80.000MB/s transfers (40.000MHz, offset 31, 16bit), Tagged Queueing
Enabled
da0: 953899MB (1953585152 512 byte sectors: 255H 63S/T 121605C)
...
It seems to report itself as SCSI-3 but dislikes to get probed for too many
LUN's...
Bye/2
