That just doesn't make sense.. x86 changes I could imagine blaming on the
irq.c changes (and even that I'd have a hard time doing), but that file
isn't even used on m68k..
The only common theme would be the generic networking code.
David, did any of the 2.1.120 patches change the way how the downcalls
into the network drivers were done? I notice that some irq disables were
changed into "bh_atomic()" calls instead, and that might certainly have
changed timings quite a lot. And maybe one of them really was interrupt-
critial rather than bh-critical (sounds unlikely, as almost everything
happens in bh's, and almost nothing happens in interrupts)?
