My system performs remote data logging. Is there a way to guarantee reboot on a kernel panic? I plan to use the WDT on my system, but I don't know if a kernel panic would always halt all processes.

There's been talk of using the new kexec() functionality to do this. As I recall, it's the reason Linus wanted kexec split into two pieces (load and execute).
It looks like kexec progress has stalled but it's still listed as "before 2.6.0".

Ha! Further digging reveals that it shouldn't even be that difficult. % echo 5 >/proc/sys/kernel/panic I'm surprised you didn't find that in your search. It was new to me too.
I'm guessing that the point of the kexec behavior was to allow specification of a *different* kernel to boot in the event of a panic. (That's my main interest - using Linux as a bootloader.)
