So, if you use 32bit PowerPC, drop me a mail describing what kind of platform
it is. ("powermac G4" for eg). Also useful would be lspci output, and
the answer to "does it have ISA slots?".
Thanks,

Only the G5 (ie, 64-bit) was released with PCI-E slots. Unless somebody
is using PCI-E on a PPC32 board that's not a Mac, or is installing
32-bit Fedora on a 64-bit G5 box, there's absolutely no way that PPC32
could coexist with the 3945 or 4965. You'd also have to get a
PCI-E-to-ExpressCard or PCI-E-to-MiniCard carrier.
No PowerBooks ever had internal PCI-E minicard slots. No PowerBooks
ever had ExpressCard slots.

As far as I know, that's not possible.

I didn't think any Apple PPC machines ever had ISA as actual slots.
Whether other PPC machines from IBM or others did I'm not sure, or
whether PPC has the embedded ISA stuff like some of the newer Intel
stuff for things like the i2c bus.
Can we just disable a lot and get it reported on the list or bugs.
What options do the yellow dog guys enable in their 32 bit kernels?

Careful: our 'ISA' in the kernel also coverse the various LPC busses that
replaced it. You can get burned if you just check for slots rather than
onboard 'ISA' devices.

I have some dubious plans for that. But they are irrelevant here, as it
would require a different flavor of kernel that we build today anyway.

Has anyone looked at _why_ they are so slow? Do you have timing
information for a particular kernel flavor?
If I'm remembering correctly, local kernel builds on my G5 were quite
faster than what is in koji. Finding out why might be a good start.

Yes, some pSeries had ISA busses long, long ago. But even more recent
(post 2000 even?) pSeries machines like some of the 43p series have an
internal ISA bus that drives stuff like the floppy and sound
controllers.

We last had working support for 43p-150 machines in FC6. Something in
the kernel has broken it since, and despite good attempts to fix it we
still don't have a working kernel there.
