I have some kernel crashes which are cured by some gcc/binutils changes
which I don't believe should make any differences. I thought I could
take out the mips64 and -march patches. But wtithout them, the user
applications seem ok, but the kernel crashes in all different places.
I have to put them back in. They may be kernel bugs and my gcc/binutils
changes may just hide them.

BTW, what is the current 2.4 kernel patches for Algorithmics P6032?

Thanks.
