`panic: run_interrupt_driven_config_hooks: waited too long' on HP DV8

Hi,

I'm getting the following panic trying to boot March 5 snapshot on
HP Pavilion DV8 notebook (8.2-RELEASE GENERIC kernel seems to boot on
the same hardware just fine):

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

Any hints or additional information I should provide to troubleshoot
this?


TIA,
