Unable to read firmware registers on crash?

I am trying to debug a case where firmware occasionally crashes and
the driver cannot read any crash dump to debug problem further.

Any idea what might be the problem and how I might could read info
from the firmware (or hack firmware to deliver the crash info in some
other means...maybe though a previously reserved piece of memory on
the host??)
