My original post was user error and not acutally a bug. I didn't
realize that there was another patch I need to apply to rc3 to get the
latest scsi drivers and error handler code. Alexis clued me in. Now
the error handler appears to be working properly. I included a sample
at the bottom of this email.
I am still seeing the disk go offline if I run i/o performance tests on
sas disks connected to the aic94xx (sequencer version 32). It doesn't
happen right away. The i/o tests will run for several hours before it
fails. Eventually you see the filesystem abort and then be remounted as
read only.
