[Summary]
Touchpad and keyboard are not working after installing 5.11.0-35 from proposed.
I tried to use 5.11.0-34, keyboard and touchpad are working.

I found there are some error msg through dmesg, not sure are they related to this issue?

Not sure the serio message is relevant. Interestingly the journal also contains a 5.4 boot which has the same. There is a more serious problem even before.

inspiron-5480-c1-201807-26321 kernel: WARNING: CPU: 2 PID: 369 at mm/page_alloc.c:4975 __alloc_pages_nodemask+0x268/0x300

This is caused by dell_wmi_sysman requesting an allocation which is beyond the allowed order. The date seems to come directly from the bios. None of that happens for the 5.11.0-34 kernel. Though we had feedback that on the same hardware we do not get issues running the same kernel version on hirsute (the kernel then is also built in hirsute space).

The allocation failure seems to lead to a crash later on (still part of loading the dell-wmi-sysman module. There was one change in the kernel which addresses how ACPI attributes are treated:

41a8457f3f6f "ACPI: DPTF: Fix reading of attributes"

However there seems to be no follow-up yet on it upstream. Nor seems the same change that is also present in the parent hirsute:linux kernel to be causing issues for hirsute. IT still could be a compiler issue because the hwe-5.11 kernel is compiled in focal user-space. Therefor it would be interesting to see whether the parent hirsute kernel, when installed under focal user-space is also showing problems or not.

After installing hirsute kernel -36 in Focal, touch pad and keyboard are still not working. I also tried to install -36 kernel only without dist-upgrade and disabled proposed then they're working, so I guess it's not a kernel regression.

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