When you get to the end of the tape writing (not the end of the tape), and the tape begins to rewind - you'll get very similar messages popping out and potential SCSI-bus lock-ups. I didn't notice the problem until I installed 2.1.5-STABLE, which has a lot of 2940 related changes. I'm actually using an Adaptec 2940UW... I thought you'd like to know you weren't the only person seeing this... and, I believe the pertinent people are aware there is a potential problem... I'm sure, as soon as more information is availble, you'll hear about it. - Dave Rivers - > environment: > FreeBSD 2.1.5 > IWIll P55TU with Adaptec 7880 (2940 UW) > enable disconnection for HDD - no > termination: Low-Off/ High-On > IBM HDD: DFRSS2W (wide SCSI drive) connected to wide connector > autostart - on > D TI SY - on > TERM PWR EN - on > TOSHIBA SCSI-2 CD-ROM connected to 50pin connector > terminated via pluged terminators > > syslog: > ------- > sd0(ahc0:0:0): timed out in command phase, SCSISIGI == 0x4 > sd0(ahc0:0:0): asserted ATN - device reset in message buffer > sd0(ahc0:0:0): timed out in dataout phase, SCSISIGI == 0x0 > ahc0: Issued Channel A Bus Reset #1. 2 SCBs aborted > sd0(ahc0:0:0): UNIT ATTENTION asc:29,0 > sd0(ahc0:0:0): Power on, reset, or bus device reset occurred > , retries:3 > > swap_pager: I/O error - pagein failed; blkno 11152, size 8192, error 5 > vm_fault: pager input (probably hardware) error, PID 92 failure > sd0(ahcsd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:3 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:2 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:2 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:1 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:1 > sd0(ahc0:0sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:4 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:3 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:2 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:1 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , FAILURE > swap_pager: I/O error - pagein failed; blkno 11152, size 8192, error 5 > vm_fault: pager input (probably hardware) error, PID 92 failure > :0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , FAILURE > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , FAILURE > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:4 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:4 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:3 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:3 > 0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:4 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:4 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:30:0): Logical unit is in process of becoming ready > , retries:4 > sd0(ahc0:0:0): NOT READY asc:4,1 > sd0(ahc0:0:0): Logical unit is in process of becoming ready > , retries:3 >
