Fwd: RTEMS core: bad work with _Watchdog_* ?

[Thomas Doerfler]

Hi Gerke,

I think it is sufficent to get the latest 
"cpu_asm.S" file from the current snapshot, 
hoping it has no further changes since 4.5.0...

I also like to stick to a certain rtems version 
during development, so that's also been my way to 
move to the corrected version of the interrupt 
code.

Bye,
	Thomas.

this fix of the m68k interrupt entry code? Then I'll have a look at the snapshot to get this new code into my 4.5.0 tree. I'd love this to be the answer to my interrupt problem!
