Hello, 

I've tried again the latest version of if_bge.c on my HP 6710b laptop
with no results, even after setting hw.bge.allow_asf="0". I've also
tried with the debugger and it seems to panic when calling free() in
device_probe_child.c (IIRC). Then I #define'd BUS_PROBE and the freeze
occurs after displaying something like "devclass_alloc_unit: now: unit 0
in devclass bge".

The 7 Beta 1.5 install CD hangs also when loading the driver.

I have a coredump made from whithin the debugger with the exact place
where the faulty free() occurs, so I can provide more exact info if
someone is interested. I just hope this is not a heisen-bug.

Best regards,
Cristi
