Kernel 4.9 bugs

Everykind of kernels from 4.9 line reports this kind of bug (on 2 different laptops one with AMD Piledriver, the second with Intel Silvermont):

[Firmware Bug]: CPU0: APIC id mismatch. Firmware: 10 CPUID: 0
[Firmware Bug]: CPU0: Using firmware package id 1 instead of 0
[Firmware Bug]: CPU1: APIC id mismatch. Firmware: 11 CPUID: 1
[Firmware Bug]: CPU1: Using firmware package id 1 instead of 0
platform wdat_wdt: failed to claim resource 1
ACPI: watchdog: Failed to create platform device

Tested on linux, linux-zen, linux-bede (herecura repository) and even on linux49 (from Manjaro).

Re: Kernel 4.9 bugs

Yep same with me. Resulted in a borked system after updating to testing. Amd fx-8350

I don't really know what I'm doing.

Re: Kernel 4.9 bugs

Three bugs related to kernel 4.9 :

https://bugs.archlinux.org/task/52246 -> doesn't boot on some intel CPUs
https://bugs.archlinux.org/task/52271 -> same here
https://bugs.archlinux.org/task/52238 -> DRM regression in zen kernels.

Looks like 4.9.x is really in a bad shape somewhere

Re: Kernel 4.9 bugs

Just wondering if Kernel 4.9 is a long way off due to it being buggy is it not worth bumping the kernel packages to the latest 4.8 release? 4.8.13 has some very nasty bugs that affect some Dell hardware...

For bug 192111 patch is indeed available, but I think we'll have to wait for linux 4.9.4 or 4.9.5 to get a working kernel with some Intel CPUs.

Well, 4.9 is blocking 4.8.xx ultimate updates. It is annoying to stay polite.

Re: Kernel 4.9 bugs

Be aware that you also need linux-firmware from [testing].

Re: Kernel 4.9 bugs

Is 192111 waiting on feedback from patch testing?
There is also no confirmation from pb or brittyazel that

[Firmware Bug]: CPU0: APIC id mismatch. Firmware: 10 CPUID: 0

is fixed in 4.9.2+ (now that 4.9.3 is out)
Also https://bbs.archlinux.org/viewtopic.php?id=221755 which seems different again.
190061 not a new issue with 4.9 but seemed to coincide with arch stopping following 4.8.y series.
Edit:
I see 192111 now has one confirmation that the patch compiles with 4.9.3 and fixes the issue.

You can add 4.9.4 to your list. And patch for bug 192111 is on its way to be included in both linux 4.10-rc4 (or 5) and - maybe ? - linux 4.9.5
