SCB - timed out on FreeBSD 4.10-p2

[Dave Hayes]

I'm wondering if this has been seen before exactly? I'm seeing the
following on a FreeBSD server:

/kernel: (da1:ahd1:0:0:0): SCB 0x12 - timed out
/kernel: (da1:ahd1:0:0:0): Other SCB Timeout
/kernel: ahd1: Recovery Initiated - Card was not paused

Googling around a bit gave me a weak theory that the seagate firmware
might be defective, but that diagnosis is several months old. Can
anyone shed some light on this? I can provide more data on request.

The server has the following relevant devices on it:

Exaggeration is a standard peculiarity of man. To deprecate
is often a form of exaggeration which people do not notice
because it appears to be its opposite.
