Hardware debuggers for PPC74xx G4 CPUs

[Gerhard Pircher]

I'm trying to debug a kernel lockup that occurs on my machine with all kernel
versions >2.6.16. I don't have a clue what the root cause of this lockup is,
thus I'm thinking about using a hardware debugger. Can anybody recommend a
reasonably cheap hardware debugger that works with G4 CPUs and can interact
with GDB/DDD?

regards,

Gerhard
