[OpenIndiana-discuss] strange reboot behavior: deadman timeout

[Richard Lowe]

If you get a crash dump, can you provide it?  Is this a machine with
an x2apic?  If it is, have you disabled it?
(there's at least one known issue with complete, solid, system hangs
on machines with x2apics).

That said, if you were triggering the deadman regardless something is
clearly wrong that _is not_ the x2apic issue, possibly in addition.
The crash dump would help, if you can't provide a crash dump for
whatever reason, it'd be nice to see the output of:

sudo savecore
sudo savecore -vf vmdump.0 # or .1, or .3 or whatever number the most
recent dump is
sudo mdb 0 # The same number as above

::stacks
::cycinfo -v
::cpuinfo -v

Though it's very likely this would not be useful without also having the dump.
