I just built two almost identical systems. I installed 4.2-RELEASE on both - one is beautiful, the other is a problem child. I've subsequently upgraded the problem system to 4.3-RELEASE and see the same issues. Both systems use Asus dual P-III mainboard, 3COM 3C905 ethernet, Adaptec 29160 SCSI Ultra160. There are slight differences between the systems - the one that works fine is in a tower case and uses IBM DDYS-T18350N drives and has 256MB RAM. The one that produces parity errors is in a rackmount case and uses SEAGATE ST336737LW drives and has 1GB RAM. Everything I've read points to cables and termination as the issue. I've replaced the cable and terminator but still see the problems. A new Adaptec SCSI card is on the way. There are only two SCSI devices on the SCSI bus. SCSI ID 0 is the boot device of course - when I remove the second device the problem goes away. Still looks like a cable issue. Here is part of dmesg: Waiting 15 seconds for SCSI devices to settle Mounting root from ufs:/dev/da0s1a da0 at ahc0 bus 0 target 0 lun 0 da0: <SEAGATE ST336737LW 0102> Fixed Direct Access SCSI-3 device da0: 160.000MB/s transfers (80.000MHz, offset 31, 16bit), Tagged Queueing Enable d da0: 35242MB (72176566 512 byte sectors: 255H 63S/T 4492C) da1 at ahc0 bus 0 target 4 lun 0 da1: <SEAGATE ST336737LW 0102> Fixed Direct Access SCSI-3 device da1: 160.000MB/s transfers (80.000MHz, offset 31, 16bit), Tagged Queueing Enable d da1: 35242MB (72176566 512 byte sectors: 255H 63S/T 4492C) (da0:ahc0:0:0:0): WRITE(10).
