Kernel 3.15

[xeno74]

Hi All,

I have some bad news for you. The RC 1 of the kernel 3.15 doesn't boot currently. I don't know why. I have test it with our standard patch with Olof's hack and then I have test it without Olof's hack. But without any success. I have test it with the boot argument radeon.dpm=0. But it doesn't boot. I hope I can figure out why.

First, the config of the RC 1:

nemo_3.15-rc1.config.tar.bz2

The patch with Olof's hack:

The patch without Olof's hack:

nemo_3.15-alternative.patch.tar.bz2

The RC 2 doesn't boot, either. We'll try to figure out why.

Unfortunately, the RC 3 also doesn't boot.

Darren, could you try to solve this boot problem, please? I think it's a radeon issue.

Hi All,

I have compiled the RC 4 of the kernel 3.15 but it doesn't boot.

By the way, here is a very interesting thread about Lubuntu 14.04 on a Power Mac G5 Quad: http://ubuntuforums.org/showthread.php?t=2221421

Rgds,

The RC 5 doesn't boot, either.
Darren tried to catch some serial output to get an idea where it is failing, only it's not generating any. He will try some other configs see if anything helps, but at the moment this looks like there is another early boot problem.
I try to figure out which patch is the problem for the boot issue in the git log. For example:

Kernel git version 3e75c6de1ac33fe3500f44573d9212dc82c99f59 didn't boot
Kernel git version 6d956e422bf1848e430e0ec3610096215217cb02 boots without any problems.

Hi All,

I have found out which patch is responsible for the boot problems. It's patch 9000c17dc0f9c910267d2661225c9d33a227b27e. Link: https://git.kernel.org/cgit/linux/kerne ... 33a227b27e
