Re: mysterious process scsi_eh_5

Thanks for catching me that fish, but tomorrow I'll be hungry again.

So [...] usually means kernel thread. And if I see that and want to know more about it, what documentation would I start looking at? If you hadn't just told me what scsi_eh_5 was, where would I look for a clue? Is there a good google search that would have told me this?
Thanks,
Dave

 "ps" prints brackets when process arguments are not available to read.
This is typical for kernel threads. scsi_eh_5 is a kernel thread, a SCSI
Error Handler. It is spawned for each SCSI host in computer (there
should be EH thread for each /sys/class/scsi_host/* )

 Probably yes. USB Mass Storage uses various SCSI command sets. Just
like SATA, FC.
