Hi there,
Justin, Ken,
I still have bus resets while doing a tar -czf from my usr/obj to
an nfs mounted filesystem for example.
This is a problem I noticed in old-scsi system and though it was solved by CAM.
[How] Was it solved? I know this bug is really old.
I configured the bios not to have the drive disconnected,
but the reset still happens.
