upgrade to 6.0-RC1 problem

[Alex Qin]

Hi,

I recently upgrade the FreeBSD from 5.4-Stable to 6.0 RC1.
The FreeBSD run on the VMWare GSX 3.2 with LSI Logic SCSI Adapter. 
the root was mounting from ufs:da0s1a

When I upgrade to 6.0. the FreeBSD can't mount from ufs:da0s1a

It work fine on 5.4-Stable.

the problem seems cause by the GEOM managed disk device can't us the LSI Logic SCSI Adapter.
the following is capture from the screen:

mpt0: <LSILogic 1030 Ultra4 Adapter> port 0x1080-0x10ff mem 0xf4000000-0xf4000ffff irq 9 at device 16.0 on pci0
mpt0: [GIANT-LOCKED]
mpt0: MPI Version=1.2.0.0
mpt0: Unhandled Event Notify Frame. Event 0xa.

Mounting root from ufs:da0s1a
 
 Manual root filesystem specification:
 <fstype>:<device> Mount <device> using filesystem <fstype> 
                               eg. ufs:/dev/da0s1a
 ? List valid disk boot devices
 <empty line> Abort manual input

mountroot> 
 
I tried: Input ?
List of GEOM managed disk devices:
  cd0 acd0
 
 mountroot> ufs:/dev/da0s1a

but that fails too.

AS compare:
under FreeBSD5.4-Stable:
List of GEOM managed disk devices can show many da device, such as: da0s1a ...
the following is captured from the 5.4-Stable boot screen:

mpt0: <LSILogic 1030 Ultra4 Adapter> port 0x1080-0x10ff mem 0xf8000000-0xf8000ffff irq 17 at device 16.0 on pci0

Only one line information about mpt device.

does the MPT device cause this problem?

any assistance would be gladly appreciated.
