The stat subcommand should always be the first command run when examining
a system crash.
The trace -m subcommand
The trace -m subcommand gives you a kernel stack traceback.
This is typically the second command you will run when examining a system
dump.
This subcommand provides information about what was happening in the kernel
when the failure occurred. The trace -m subcommand provides a history of
function calls and interrupt processing at the time of failure. If the failure occurred
while interrupt processing was going on, this subcommand will be very useful in
determining the cause. This subcommand traces the linked list of mstsave areas.
The mstsave areas basically contain a history of what interrupt processing was
going on in the system.
The machine state save area, or MST, contains a saved image of the machine’s
process context. The process context includes the general purpose and floating
point registers, the special purpose registers, and other information necessary to
restart a thread when it is dispatched. For example:
> trace -m
