RE: iopkt hangs after loading 2 differnet drivers
> io-pkt hanged ...
This kind of problem is generally pretty easy to diagnose.
Run pidin, and get the pid of io-pkt. Then run
# dumper -p N
where N is the pid of io-pkt. This will create a core
file, just as if io-pkt had faulted.
Then, using gdb, load the corefile and do a backtrace
of each of the threads.

Please check out this thread:

You have to do more than spit out a debug message in your
quiesce_callout.
