Hi,

We're experiencing a kernel hang on a 6.x quad processor Sun amd64
based system.  We are able to reproduce it fairly reliably, but the
environment to do so is not easily replicatable so I cannot provide a
simple test case.  However, I have been able to build a debug kernel
and when the system "hangs", I can break to the debugger prompt.  But
once there, I'm not sure what to do to isolate where the system is
hung up.  I have confirmed that the hang occurs in both SMP and
uniprocessor mode.  Here are some system details:


I think you'll need to ship this machine to my house for further um....erm, diagnostics, yes, that's it ;)


On a more serious topic, can you paste the output from:


ddb> show pcpu
ddb>allpcpu
ddb>traceall
ddb>show alllocks
ddb>show lockedvnods

Just curious as to whether those would show more info, because you're right, that trace is about as informative as new printer paper :)


Cheers
