New kernels

[Hypex]

Okay so I've tested up to the RC1. I can confirm alpha 4, 5 and 6 do have issues. In my case I booted with an initramfs which allowed me to drop to a shell after booting broke. There was a similar crash but, on my X1000 the bad pointer was at 0x00000050 and not at zero if I read it correctly, Given the latest info on the crash I do wonder why it appears that only PPC is affected or our builds anyway.

I also notice, more apparent on alphas, is a delay in Fienix desktop. The menu is unusable until it fully loads. It keeps cancelling menu navigation before it's loaded all its icons. Kind of annoying trying to use it.

The RC1 boots again as expected.

Hypex,

Thank you for testing.

@All
Wu Hoi Pok has released a patch because of the Radeon DRM driver issue.

I compiled a new RC1 of kernel 6.12 with this patch today. Please test it.

I tested this and it fails for me. Two penguins show up and there is no text output. In fact this happened with the previous working RC1 as well.

The latest ends up in a crash. It does boot into a shell where I can log in. I was able to save uname and dmesg output.

Hi Hypex,

Many thanks for testing the RC1-2. I reported this issue to the kernel developers today.

The RC1 boots again as expected.

You wrote "In fact this happened with the previous working RC1 as well.". I don't understand. Does the RC1 boot or not?

Thanks,
Christian

Great. Will get it sorted.

Too many RC1 references The RC1-1 boots. The latest RC1-2 you released fails. The RC1-2 doesn't boot.

What I meant was the penguins. In both the working and failed kernel there are double penguins, With no text output on screen as kernel boots.

[xeno74]

The RC1-1 boots.

The RC1-2 doesn't boot.

OK, good to know.

FYI: Kernel doesn't boot after DRM updates (drm-next-2024-09-19)
