Kernel 5.13 fails to work with lots of hardware (HP Zbook)

[a1291762]

The Internal display does not work. External monitors connected via Thunderbolt down continue to work.
The trackpad does not work. The keyboard does work.
The Ethernet on the Thunderbolt dock does not work.

Booting the 5.11 kernel allows everything to work.

I'm not sure how useful the automatically-attached files are since I had to boot with 5.11 in order to get the network working.

I note that /dev/input/event7 to event26 are missing with kernel 5.13.
The Thunderbolt dock Ethernet seems to be this device (missing with kernel 5.13).

    r8152 6-1.3.3:1.0 enx3c52821a24c3: renamed from eth0

I see what looks like the laptop's internal ethernet showing up though. I didn't think to move the Ethernet cable to that port to see if it would work.

My external monitors (BenQ FP937s and Samsync SyncMaster) show up for both kernels. Interestingly, I don't see the internal panel showing up under either kernel? But it works with 5.11 and not with 5.13.

I only see this with 5.11:

    (II) modeset(G0): using drv /dev/dri/card0

And then some EDID probing, that maybe includes the internal panel?

I have even worse problems with an AMD 4700U machine (iGPU only) that just crashes into B/W screen noise at booting. HWE kernel series 5.8 and 5.11 work perfectly fine, but I see this massive regression with 5.13.

Status changed to 'Confirmed' because the bug affects multiple users.

[Ras (rasdpm)]

Note that I already tried removing the additional clevo_xsm_wmi kernel module for the RGB keyboard, but that doesn't change the problem.
Also, the following error messages are there for both 5.11 and 5.13:
kernel: amdgpu 0000:04:00.0: Direct firmware load for amdgpu/renoir_ta.bin failed with error -2
kernel: amdgpu 0000:04:00.0: amdgpu: psp v12.0: Failed to load firmware "amdgpu/renoir_ta.bin"

[Ras (rasdpm)]

Here the dmesg for a 3400G machine with iGPU only where there is no crash with the HWE kernel 5.13. That's Zen+ instead of Zen2 and Picasso iGPU instead of Renoir.

And here the kern.log for that 3400G machine on 5.13.

I don't know what happened, but apparently my system doesn't want the 5.13 kernel installed anymore. I just managed to remove it (and the related NVidia kernel module packages) without causing any conflicts or triggering any meta-package complaints...

Which is great, because it means I don't have to hack grub into booting the 5.11 kernel now :)

Update: the 4700U graphics crash problem persists with the new 5.13.0-23 HWE kernel.

[Ras (rasdpm)]

Update: 5.14 works properly, linux-oem-20.04d kernel 5.14.1013.13 tested on 4700U.

[Ras (rasdpm)]

Update: the 4700U graphics crash problem persists with the new 5.13.0-25 HWE kernel.

[a1291762 (a1291762)]

My machine was pushed the 5.13.0-25 kernel today but this time it did not cause everything to break. All of the things I originally reported as broken on my HP Zbook are now fixed.

The internal display works.
The trackpad works.
The keyboard works.
The Ethernet on the Thunderbolt dock works.

My system has an NVIDIA GPU (looks like a Quadro T1000) so I do not see the 4700U graphics driver crash that rasdpm reports.

I have a HP ZBook and 5.19 has not solved this for me. I cannot use my external monitor unless I revert back to 5.10, I have not attempted 5.13, but I don't think it matters that much, I would just like to use the up-to-date kernels if possible :)
