The patch in the PR allows our two Symbios 875 boards to work with
FreeBSD-6.2-recent.
However, the machine continues to suffer from the "spin lock held to long"
panics every few days. Usually, there is a double-panic, which prevents crash
dump from occuring. But this morning it succeeded.
The full trace is available at
http://aldan.algebra.com/~mi/bonkers-crash-4.txt
The panic is from kern_mutex.c. The value of the delay-counting i is, no
surprise, exactly 60000000.
I'm not sure, if it is the sym-enabling patch, that causes the problem, or
something else. Either way, it would be very useful for an expert to look at
it -- and commit the (possibly modified) patch too.
