Dell PERC5 (SAS 5) controller boot flr

[Thomas Kindig]

FreeBSD 6.2rc1 installer is able to access controller/drive for 
purposes of install, but cannot access installed system following reboot.

The system is a DELL PowerEdge 1950 with a SAS 5 controller, single 
180G ATA HD.

Following a successful install and reboot the system fails to come 
up. The boot process ends with the following (very slowly, so that I 
could spell it all out):

mpt0: mpt_cam_event: 0x16
mpt0: Unhandled Event Notify Frame. Event 0x16 (ACK not required).
unknown: timeout waiting for read DRQ
bce0: link state changed to DOWN
bce1: link state changed to DOWN
acd0: CDRW <HL-DT-STCD-RW/DVD-ROM GCC-4244N/B101> at ata0-master UDMA33

Is there a bug report on this? Any prognosis for a fix before 6.2-RELEASE?
