I'll assemble a serial cable and recompile the kernel with debugging components and come back to you as soon as I've got more details on that. > Could you try compiling and running without the PREEMPTION kernel option?

No, first board had P-III 600 MHz, second had AMD k6/2-500, both single CPU. > Probably the most valuable information would be the stack traces as indicated above, however. Will make the serial cable and come back to you (takes some hours...). Thanks, Volker -- GPG/PGP fingerprint: FF93 13A1 2477 B631 E953 06DF 4C49 ADD9 E4BF 79B1
