This is a problem with the new PCI code. I had some hacks in there for a
long time to adjust the PCI-bus base relative values that the PCI config
space for those cards gives us. I had to convert them to absolute addrs.

Quite the opposite. The 2.4 and 2.2 BK kernels are quite stable. The
kernels that Paul keeps around (accessible via rsync) are experiments that
Paul doesn't push up to the BK tree, I believe.

Ah, the B50 I had came with a Matrox. You'll definitely need to build a
new kernel, then.
Someone has a webpage full of builds of the daily snapshots from the 2.4
and 2.2 BK trees. You may want to make the workstation and linuxppc-dev
list to find out where it is.

You can have a different endianness in an interrupt handler. When you get

I know nothing of the F40. I'm having all kinds of 2.2 trouble right now.

The claims about IBM there aren't too accurate. They're not so out of
touch. Look who they're selling rs6k's to. Big companies that want _full_
support 24/7 with AIX. They're willing to pay a lot for the support they
get from IBM.
For Linux, that's way off base but they only recently turned

Too bad they're so expensive. Someone could make a killing with cheap
commodity ppc boards.
The 4 processor rs6k smp I've been testing does quite well as it is. My
theory is that we're loosing a lot of performance on the htab contention
(if I can prove it, I'll create separate htabs per processor). If you
isolate any performance bottlenecks with SMP please let meknow.
