Yes.  Someone on the debian lists reported that some motherboards 
locked up on the tecra set when we first applied the patch, so 
I passed the info on, and he credited me for some reason --- I never saw the 
behaviour myself, and reading the patch, there would have to be something 
pretty strange about a m/boards that lock up on it --- but people reported it 
as happening at the time.

An alternative approach might be to use a zImage, rather than bzImage, but I 
suppose the kernel will not fit unless its bzImage ?

zImage kernels don't provoke the problem on tecras.

Cheers, Phil.
