Hi Thomas Doerfler,
this sound verry promissing. But I'd like to stay with my 4.5.0 tree because of all the things I might need to upgrade to get the autoconf etc. to work. I'm really looking forward to this new thing but I'd like to get my 4.5.0 going first. Could you point me out the file that was changed for 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!
