Looks like rev 0x01 means I should exchange the card for a D. No mystery there. I've never ever seen the aborts and timeouts in the 155 days this one (also a -CURRENT box from.. well.. 156 days ago) has been up which is a lot more than I can say for the next box :( ahc0: rev 0x00 int a irq 10 on pci0.10.0 ahc0: aic7880 Wide Channel, SCSI Id=7, 16/255 SCBs this is the last one with a 2940UW in it where there have been so many kernel messages (most of them from the SCSI timeouts, aborts, retries) that I can no longer see the beginning of the dmesg... I see it's a Rev C, not an E, but I still have the problems with this one that have been described earlier: sd1(ahc0:2:0): SCB 0x6 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 SEQADDR = 0x5 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa Ordered Tag queued sd1(ahc0:2:0): SCB 0x6 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 SEQADDR = 0x4 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa sd1(ahc0:2:0): Queueing an Abort SCB sd1(ahc0:2:0): Abort Message Sent sd1(ahc0:2:0): SCB 6 - Abort Tag Completed. sd1(ahc0:2:0): no longer in timeout Ordered Tag sent This one's been up for 85 days and is running 2.2.6-BETA from mid-March but has had this problem since upgrading from 2.1.5 to 2.2.[1 I think] Same symptoms with three different cables and without the AHC_ options. All of these machines have all the AHC_ options enabled right now and no CAM. -T -- TerraNovaNet Internet Services - Key Largo, FL Voice: (305)453-4011 Fax: (305)451-5991 http://www.terranova.net/ ---------------------------------------------- And Jesus said unto them, "And whom do you say that I am?"
