Hi, I have a Dell Poweredge 2200 with a scsi-scsi CMD raid-box (consisting of 3 Seagate Cheetah 4.5GB disks striped together) attatched to a 2940 controller, the relevant output from dmesg are : ahc1 <Adaptec 2940 Ultra SCSI host adapter> rev 0 int a irq 15 on pci0:18:0 ahc1: aic7880 Wide Channel, SCSI Id=7, 16 SCBs ahc1 waiting for scsi devices to settle (ahc1:2:0): "CMD TECH CRD-5330 C1-2" type 0 fixed SCSI 2 sd1(ahc1:2:0): Direct-Access 13017MB (26658816 512 byte sectors) I'm running FreeBSD-2.2.6. The system has crashed twice with these messages : Jun 27 00:29:41 feedme /kernel: sd1(ahc1:2:0): SCB 0x1 - timed out in dataout phase, SCSISIGI == 0x4 Jun 27 00:29:41 feedme /kernel: SEQADDR = 0x41 SCSISEQ = 0x12 SSTAT0 = 0x7 SSTAT1 = 0x2 Jun 27 00:29:41 feedme /kernel: sd1(ahc1:2:0): abort message in message buffer Jun 27 00:29:42 feedme /kernel: Unexpected busfree.

I've searched the mailinglist archives, but still have no clear idea as to what could have caused these crashes. The AWRE and ARRE settings were 0 before the first crash, but were set to 1 before the second crash. Any hints as to how to fix this would be most welcome.
