About FPU instructions inside the an interrupt, all registers are saved ?
You havn't forgotten fpcr, fpsr, and fpiar ?
Because if fpiar isn't saved you can destroy the context used by the motorola unimplemented instruction emulator.
For example if the emulator found a bad pointer inside the stack you can destroy the program himself (instruction after the code emulated).
Regards,
Didier.

That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
