Whenever I try to upgrade to a kernel >2.6.12-r4 (what I'm currently running), I get a kernel panic during boot. The panic reports a bad magic number for XFS (which is used on a non-critical FS) before the panic. Reproducible: Always Steps to Reproduce: 1. Compile kernel >2.6.12-r4 2. Install kernel to boot 3.

Please attach .config from 2.6.12, .config from 2.6.13, lspci output, and bootloader config. Is this machine on a local area network? Do you have access to a serial console cable and another local machine?
I just want to emphasize that I tried to upgrade from 2.6.12-r4 to 2.6.12-r5 and this issue was already there. I only bring it up now since 2.6.13 hasn't resolved the issue. So, it's not a 2.6.12 to 2.6.13 issue necessarily.

So 2.6.12-r4 works fine and 2.6.12-r5 fails?
Yes, that's what I'm saying. The problem started when 2.6.12-r5 came out since I always upgrade as soon as possible. However, 2.6.13 hasn't resolved the problem either. The kernel panic message has been the same for 2.6.12-r5 to 2.6.13-r4 which I just tried last night. I may not have tried every -r in that range, but the ones I did had the same error message.
I find this very unlikely to be a kernel bug as nothing at all storage-related changed between -r4 and -r5. It is more likely to be a misconfiguration. Please also attach your kernel .config from 2.6.12-r5
My .config for 2.6.12-r5 would have just been me running make oldconfig on my .config from 2.6.12-r4. 2.6.12-r5 isn't in portage anymore so I can't generate a .config in this manner, but if no new config options were introduced from r4 to r5 then my 2.6.12-r4, which I already attached, should be what you want.
Please download and unpack this tarball: http://dev.gentoo.org/~dsd/genpatches/tarballs/genpatches-2.6.12-8.base.tar.bz2 From the extracted files, please apply the following patches to 2.6.12-r4: 1305_ppc-ntp.patch 1905_netfilter-conntrack.patch 2900_gameport-probe.patch After applying each one, rebuild the kernel, reboot, to confirm that the system still boots (make sure you have a backup kernel incase it doesn't...). Those patches will convert your 2.6.12-r4 into -r5 so hopefully it will point out where the problem was introduced.
Please reopen when you've had a go at comment #10 (I really suspect there is more to this bug than what the report suggests)
I tried a booting a version with each patch individually and they worked. I was planning on trying 2.6.14, but I haven't had a good time to reboot.
Please reopen when you test 2.6.14, or even better, the latest development kernel (currently 2.6.15-rc2)
