run_interrupt_driven_hooks - waiting for xpt_config - booting on DL380 G6

Hello,

I'm running into difficulties booting FreeBSD 8.0 BETA2 amd64 CD image  
on a HP DL380 G6.

it freezes right after USB hubs & CD initialization with the messsage:

umass0: <Virtual CD-ROM> on usbus5
umass0:  8070i (ATAPI) over Bulk-Only; quirks = 0x0000
umass0:2:0:-1: Attached to scbus2
run_interrupt_driven_hooks: still waiting after 60 seconds for  
xpt_config
run_interrupt_driven_hooks: still waiting after 120 seconds for  
xpt_config
run_interrupt_driven_hooks: still waiting after 180 seconds for  
xpt_config
run_interrupt_driven_hooks: still waiting after 240 seconds for  
xpt_config
run_interrupt_driven_hooks: still waiting after 300 seconds for  
xpt_config
panic: run_interrupt_driven_config_hooks: waited too long
cpuid = 0
KDB: enter : panic
[thread pid 0 tid 100000]
Stopped at      kdb_enter+0x3d: movq    $0,0x687f60(%rip)
db>

keyboard freezes here, so no way I can do backtrace.

The same error is with 7.2-RELEASE bootable CD, but there it just  
freezes, no messages about waiting for xpt_config.

What's there to be done ?

I can provide remote access to iLO of this server if this would  
somehow help fix things.

Thank you,
Simon.
