I'm afraid the initial analysis is that this is a bug in the adaptec sequencer (again) which no-one has the docs to fix. Guessing about the cause, I'd say it's most likely some type of data overrun, so it might be possible to change the operating parameters of the system so it no longer trips ... > Sep 28 20:21:16 m82 kernel: scsi0 : Adaptec AIC79XX PCI-X SCSI HBA DRIVER, Rev 1.3.11 > Sep 28 20:21:16 m82 kernel: <Adaptec AIC7902 Ultra320 SCSI adapter> > Sep 28 20:21:16 m82 kernel: aic7902: Ultra320 Wide Channel A, SCSI Id=7, PCI-X 101-133Mhz, 512 SCBs > Sep 28 20:21:16 m82 kernel: > Sep 28 20:21:16 m82 kernel: Vendor: SEAGATE Model: ST373207LC Rev: 0003 > Sep 28 20:21:16 m82 kernel: Type: Direct-Access ANSI SCSI revision: 03 > Sep 28 20:21:17 m82 kernel: target0:0:0: asynchronous. > Sep 28 20:21:17 m82 kernel: scsi0:A:0:0: Tagged Queuing enabled.

You can do this by echo 63 > /sys/class/spi_transport/target1\:0\:0/max_offset echo 1 > /sys/class/spi_transport/target1\:0\:0/revalidate Which should retrigger the above domain validation but this time come back with an offset of 63. *before* getting to the mount on /dev/sdb1. If that doesn't fix it, the next steps will be to begin lowering the transmission parameters.
