maybe this fixes Bug #183338 and Bug #179427

This is same bug as #183338. As noted by Sam in #183338 just adding the lines to the config and recompiling does NOT help!!!

OK, I compiled successfully a kernel from the hardy package, with the missing:
CONFIG_BLK_DEV_IDE_PMAC=y
CONFIG_BLK_DEV_IDE_PMAC_ATA100FIRST=y
CONFIG_BLK_DEV_IDEDMA_PMAC=y
and so far it seems to work well, haven't noticed other problems too, but haven't tested extensively.
Somebody tried that already and reported it doesn't help - I understand you just added the lines to .config - that usually shouldn't be done manually but through a config frontend (menuconfig...). The thing is that these three configs depend on CONFIG_BLK_DEV_IDE=y - it must be compiled in kernel and not as module - as it is currently in ubuntu - That's why the PMAC options don't exist. Why this is so I have no idea - but once it's compiled in and PMAC can be selected it works OK.
Would be good now to advance the fix of this problem - and if more people can get the grip on a manually compiled kernel in the meanwhile we can test it to see there are no other regressions :)

I'm eagerly awaiting for a new kernel to appear in the ubuntu ports including the aluded 'fix committed' that shows in the status of this bug... it makes the powerpc ubuntu port rather unusable if one doesn't happen to be able to replace the kernel...

btw, a non-module CONFIG_BLK_DEV_IDE=y wasn't necessary in ubuntu's 2.6.22...

I checked the kernel repository, seems the following patchset is to blame:

commit 6c28c1f59dce3325d373f44766e23eb4237a74c8
Author: Tony Breeds <email address hidden>
Date: Tue Sep 11 22:28:36 2007 +0200

pmac: build fix

Ensure that BLK_DEV_IDE is built-in before allowing BLK_DEV_IDE_PMAC to
be selected.

this goes to the prelast comment of fuoco:
i would like to test your way of manually compiling the kernel 2.6.24.5 for my ibook g4 since i got the same errors as reported.

(1) could you please post the additional steps for getting the CONFIG_BLK_DEV_IDE=y option compiled in the kernel and not loaded as a module?
(i haven't done any manually kernel compiling)

(2) and is then an editing of the config files adding
CONFIG_BLK_DEV_IDE_PMAC=y
CONFIG_BLK_DEV_IDE_PMAC_ATA100FIRST=y
CONFIG_BLK_DEV_IDEDMA_PMAC=y
still necessary?
