ppc-development-kernels > 2.6.3_rc2-r1 won't boot on my system (PowerBook G4 867Mhz 12"), the boot process hangs after mounting the proc filesystem. It does not happen with <= 2.6.2-r1 and it's always reproducable. PPC kernel developer Benjamin Herrenschmidt says it's userland and not kernel related, please read http://lists.debian.org/debian-powerpc/2004/debian-powerpc-200402/msg00519.html . At least another person on the gentoo ppc forum has the same problem with a Pbook 867 MHz and an iMac 233 MHz. Simon
Thanks for reporting. I was uploading the new 2004.0 release which features nothing but 2.6.3-r2 kernels. I shall add a fallback 2.4.24 kernel too. We'll have to start producing liveDVDs soon to accomodate for all these kernels and the boot.msg explaining options for each kernel ;-) I have cc'ed zhen@gentoo.org and drobbins@gentoo.org, since this bug might cause a small (few hours) delay for the ppc release. Pieter
I added a fallback non-modular 2.4.24-r2 kernel for non-G5 machines on the livecd. Boot livecds using "fallback" on faulty machines. This boot option will only be advertized in the ppc release notes because 2.4 accepts different args (video=radeon instead of video=radeonfb) and I don't have enough room in the yaboot boot.msg to explain those.
Unfortunately, adding a fallback kernel is not possible due to 2.4.24 not having support for latest gcloop. My first guess would be that this is a libc related problem. (I've observed a similar userland kernel locking behaviour but with devfsd. The livecd has a debug environment now (pass debug as kernel argument) which spawns a shell inside the initrd. I've made sure the initrd has enough tools to install gentoo. If the debug environment hangs, the problem is probably a kernel problem and not user space. Could you try booting 2004.0/PPC passing 'debug' if the normal booting process hangs? Pieter
I'd love to help you but I can't find a 2004.0/PPC livecd image, all mirrors I checked have empty experimental/ppc/livecd/ directories. Simon
Will ping when they are online. No worry
Im running fine on a 2.6.3 kernel g4 pb 800mhz kde 3.2 $uname -a Linux hephaestus 2.6.3_rc3-benh1 #2 Mon Mar 1 15:11:08 CST 2004 ppc 7455, altivec supported PowerBook3,4 GNU/Linux $ls -l /etc/make.profile lrwxr-xr-x 1 root root 40 Mar 1 16:21 /etc/make.profile -> /usr/portage/profiles/default-ppc-2004.0 $kwin --version Qt: 3.2.2 KDE: 3.2.0 KWin: 3.0
Ok, 2004.0 livecd made things a bit clearer for me regarding this situation: On a dual G4 867 machine with an nvidia card, mounting /proc locks up If you replace the nvidia card with an ati card, and reboot /proc mounts perfectly. I think that rebooting the livecd with the nvidia card with video=ofonly as kernel arguments should prevent /proc mounting to lock up the system.
Ok, 2004.0 livecd does not work. video=rivafb results in green and pink lines on the monitor (as expected; rivafb seems to be broken some time now). video=ofonly is better but still locks on mounting /proc. Simon
Any suggestions for producing a livecd which doesn't have this problem? What is the latest 2.6 kernel ebuild that doesn't have the problem. cc'in lu_zero to integrate gcloop support into that ebuild. Any word on benh's opinion, now that we've managed to reduce link /proc to rivafb?
the latest patch should work with any 2.6 kernel non -mm you can find it on dev.gentoo.org/~lu_zero/gcloop still I'd like to have that problem solved with a newer kernel point to me the last known working kernel and I'll update the ebuild
Wild guess: could this have anything todo with the /sys directory missing?

However, no one reported this on lists.debian.org/debian-powerpc, so I really think this is a Gentoo bug ... BTW, as I mentioned in my first message, the latest WORKING kernel is ppc-development-sources-2.6.2-r*. Simon
I can confirm that the stock 2.6.4 kernel from kernel.org works on my PowerBook 12" (867). I was also suffering from this bug with 2.6.3-benh2. (hanging on /proc mount)
luca, can you see to it we have a 2.6.4 kernel available asap? I'll update the bootable iso's right away.
2.6.4 works for me, too. Benh's tree is now almost identical to vanilla anyway, right? However, I am not able to load the snd_powermac module with a stock 2.6.4 kernel, so I wouldn't include that one on the livecd (better than 2.6.3, though). Could someone test and confirm this, please? Simon
could you paste a dmesg? Alsa should work fine (I'm still rebuilding my ppc after a bad power failure so I can't test in short time)

Ok, please forget my last post. Everything works fine after downgrading to stable gcc and libc (3.2.3). Include 2.6.4!
One experimental ppc livecd with 2.6.4 coming up. Luca, is your gcloop thing in this kernel? I'll post the livecd kernel .configs here in a (long) minute. Feel free to review.
Created attachment 28061 [details] 2.6.4 livecd kernel .configs (tar.bz2) tar.bz2 file containing all 2.6.4 kernel .configs. Please note that this is against regular development-sources-2.6.4 without gcloop integrated. An ebuild revision will be needed for integrating gcloop I guess.
there already is a patch in my home at d.g.o and an experimental kernel 2.6.5_rc2-ben0 has been tested here and is about to be in cvs (hopefully)
gentoo-dev-sources and development-sources no longer have this issue.
