When I reboot (or halt) my 3.0-RELEASE system, I get the following message:

Syncing... 4 4
(da0:ahc0:0:0:0): SYNCHRONIZE CACHE CDB: 35 0 0 0 0 0 0 0 0 0
(da0:ahc0:0:0:0): ILLEGAL REQUEST asc:20,0
(da0:ahc0:0:0:0): Invalid command operation code field replaceable unit: 14
System halted...

I searched the mailing list archives but I couldn't find anything about the
asc:20,0 error (there's plenty about asc:24,0 errors). Can anyone tell me
what's up?? Attached below is my dmesg output, please let me know if you
need more information...


Cheers,
Jeroen
