Regarding the pmac 8500, I'd appreciate some tests with the kernel at bk://ppc.bkbits.net/linuxppc-2.5-benh Also, please CC me issues relative to PowerMacs in general, or at least CC them to linuxppc-dev, as I may miss them in the lkml traffic. > Outstanding issues for PowerMac 8500 > > 'drivers/block/swim3.c' won't compile, seems to be missing a couple of > #includes's (and still gets a couple of warnings).

Right now, Linus tree is frozen regarding my driver updates though, and it's ok as far as I'm concerned, I think we'll have pmac support fully merged with 2.6.0. > Many other modules get compilation warnings.

There are several problems with controlfb and the new fbcon that I haven't fully figured out yet. Though it works for me when I boot (but strangely fails when I switch back to VT from X). > X eventually resets it to good video mode on test7-bk7, but X doesn't work > with an ADB keyboard (and it even doesn't get that far under -test8) Ah ? Works fine here. > Currently can only test over network (and as noted, test7-bk7 was last > kernel i tried that even got that far. > > May no longer fit on floppy, somewhat dangerous given i can't boot from CD > (not even MacOS) and have RAID5 root/usr. I fixed vmlinux.coff so it boots from network at least, quik should work with small kernels, but I posted a quik patch that may help with larger kernels. I plan to add yaboot support for oldworld sooner or later that will deal with that issue as well.
