Wow... sounds... painful.  Almost like your SCSI controller is just
acting up.  The host_stat message might be an indicator of that.  That's
not really normal at all.  If you SCSI controller is getting flaky,
that could _definitely_ cause file system problems... I recently had
that problem with an EISA 1742 ... right before it ate a bunch of file
systems, and then refused to let the machine boot (BIOS wouldn't even
come up... ouch...)

I use a BusLogic 958 quite happily.
