ProLiant DL360 G4p: ciss(4) boottime oddity

Wed Oct 18 20:31:31 PDT 2006

ehlo

I've got several ProLiant DL360 G4p servers running RELENG_6.
Everything is ok except boottime: boot process becomes frozen for several minutes after these messages

Oct 18 16:38:35 siziph kernel: da0 at ciss0 bus 0 target 0 lun 0
Oct 18 16:38:35 siziph kernel: da0: <COMPAQ RAID 1  VOLUME OK> Fixed Direct Access SCSI-0 device
Oct 18 16:38:35 siziph kernel: da0: 135.168MB/s transfers
Oct 18 16:38:35 siziph kernel: da0: 286095MB (585922680 512 byte sectors: 255H 63S/T 36472C)

Several minutes later boot process proceeds

Oct 18 16:38:35 siziph kernel: GEOM_LABEL: Label for provider acd0 is iso9660/FreeBSD_Install.
Oct 18 16:38:35 siziph kernel: Trying to mount root from ufs:/dev/da0s1a

One of those servers (DL360 G4p) still out of production, so I can utilize it for investigation on the trouble. Are there any developers/hackers who interested in solving of the trouble?

Also I would be glad to receive advises since I ain't kernel hacker :)
