Remote debugging doesn't always work for unpredicatable bugs. Not
everybody has a spare machine to do the debugging. The best approach
is the in-kernel debugger - something Linus has irrationally resisted
for a long time.

SGI's kdb looks pretty good - I haven't used it myself though. I like
FreeBSD's Mach derived debugger too. When the panic happens, it drops
into the debugger for you to examine the state of the system. With
ksymoops, you're limited to what is dumped on the screen - which is
often insufficient information. SCO UnixWare ("The UNIX"), the other
OS I've worked on also has a solid kernel debugger (kdb).
