> hello,

> I am running into a problem with SCSI after I moved from version
> 2.2.2-RELEASE to 2.2.6-RELEASE.  The SCSI hard drive consistently locks
> up after some usage such as writing or reading to the hard drive. The
> error is severe and requires a cold boot to get my machine up again.

> This is the error message:

> sd0(ahc0:0:0): SCB 0x0 - timed out in dataout phase, SCSISIGI == 0xe6
> SEQADDR = 0x130 SCSISEQ = 0x12
> SSTATO = 0x2 SSTAT1 = 0x13
> sd0(ahc0:0:0): abort message in message buffer
> sd0(ahc0:0:0): SCB 0x1 timedout while recovery in progress
> sd0(ahc0:0:0): SCB 0x0 - timedout in dataout phase, SCSISIGI = 0xf6
> sd0(ahc0:0:0): no longer in timeout

State-Changed-Why:  
Timeouts in data phase usually indicate a cable or termination problem. 
The error recovery code in the new CAM SCSI layer should ensure that 
the system does not lock up even if an error of this kind occurs.
