That makes things more complicated... I'll have to look at the patch then
to see what's going wrong. Not that I'll probably find anything useful; I
spent weeks looking at the SCSI problem on the SE/30 only to have Michael
point out the obvious problem the first time he saw it.

All my kernels up till the last one were generated on a Power Mac 7350
with gcc 2.95.2. Now I'm cross-compiling on my Intel box also running gcc
2.95.2. I suppose that could also be related to why you're having
problems. I'll back out the patch and compile a test kernel. I'll post a
URL when it's done.
