>Description:
Any command generating IO on the drives connected to the ATA133 channel of the SATA150 controller triggers a lock-up. There is no output on the terminal and the only option is a hard reset. First, it seemed to be a problem with vinum, but later study found it to be reproducable with 'dd if=/dev/ad8s1e of=/dev/null bs=1m' and similar.
Similar commands running on the SATA drives work flawlessly.
The drive in question is known good, since it was just taken off another controller and moved to the SATA one.
The problem was seen on both 5.1-RELEASE and CURRENT.
4.x was not tested since it didn't support the SATA controller.
The controller has been replaced with the same result.
>How-To-Repeat:
dd if=/dev/ad8s1e of=/dev/null bs=1m
Most traffic to a vinum array containing drive on the failing channel.
>Fix:
None known.
