Bug 177108

When upgrading from FreeBSD 8.2-STABLE #0: Sun Sep 25 03:26:06 CEST 2011
to FreeBSD 9.1-PRERELEASE #0 r243780M: Sun Dec  2 22:57:58 UTC 2012 we
found that the a number of devices over two SUPERMICRO AOC-SAT2-MV8 64-bit
PCI-X133MHz SATA II (3.0Gb/s) Controller Card started to experience
timeouts. They work just fine under 8.2 but are unusable due to the
timeouts in 9.1.

Disks are direct attached, no port multiplier.

Problem devices are ada1, ada2, ada8, ada9, ada10, ada11.

Errors are a mix of these two on the affected devices.
mvsch8: Wait status 50
mvsch8: timeout waiting for write DRQ
