I think I am making the issue confusing. Using the same hardware, each time--
Both in UNi Processor mode and SMP, all works fine. The hifn card does not
RELENG_6, in uni processor mode the card does not lock up. Recompile to
SMP, it locks up pretty quick.
However, its not a deadlock issue like the previous HiFn problems I have
run into. I am guessing its some sort of interrupt routing issue as the box
totally shuts down in some strange suspend state. (See the thread
6.0-CURRENT SNAP004 hangs on amr (patch))
