what would happen if you simply mask splhi (say you replace with a
return)? that way, wont it be possible to see atleast whether it
progresses?

i am not an expert in this area but i remember i faced similar problem
when i tried with an x86 box. in my case, the board was freezing during
bootup and i found that it happened when the ethernet interrupt tried to
do locking or so which led to splhi it caused the problem. and it happened
only when i enabled the third ethernet port (all being Reaktek 8139C). it
was fine as long as i used just the first two ports. i tried this
experiment many years before and i vaguely remember i tried to mask splhi.

thanks
dharani


in my case, i fugured that it was working fine as long as i use upto two
ethernet ports.
