Same problem here, (Lenovo ideapad Flex 5 -14ARE05, Ubuntu 22.04.3 LTS),
although it did work JUST ONCE, randomly, in ~two years of ownership,
about a couple of months ago. The "i8042.nopnp=1 pci=nocrs" solution

Few hours after posting I got the 6.5.0-14-generic update.
So I'll test it out for a while and see if the issue persists or if it's fixed.

Touchpad often stops responding after having the laptop(Lenovo Yoga slim

the bug 216565 mentioned is a kernel.org bug number:

It could be awesome if some of the Ubuntu Kernel devs help us to test
the 5.15 kernel with the patch.
I wanna try to build a custom kernel with the patch but I don't have
time and I'm not an expert with it.
Someone can help us with this?

Yeah...I'm agree Michael. At least in 20.04 that workaround was working

It has never been no problem. A bug that can be solved by a workaround
that works most times with many people is not solved.
In my opinion the case can be closed when the new Touchpad used by

Hello there.
the pci=nocrs on Ubuntu 22.04 doesn't allow boot. So this is again a

Please test a kernel build with this patch, combined with adding
"pci=no_e820" added to the kernel commandline. See comment 133 for more
details.

This is a follow-up to comment #123
Sorry for the long silence on this bug. I was hoping one of the upstream
pci-subsys devs would help out with this...
Since that did not happen I've been looking into fixing this myself now.
I've come up with a solution which still involves a kernel cmdline

I had similar issue.
Lenovo Ideapad 5 14ARE05 dual boot Windows 10 and Ubuntu 20.04 (Kernel 5.11
after update)
Solution steps:
(1) Update your Ubuntu 20.04 installation with all the latest update.
This should update your Kernel too (mine updated to 5.11).
(2) Reboot
(3) Go to Windows 10
Can we get a fix after over a year now? I think we have enough people
suffering to deserve a fix for this bug.

@Jayden: Did you verify the image? Ubuntu 20.04 worked on my 14IIL05, of
course without touchpad. I know that all that is something off topic,
but we should clarify that very fast, so we know, if Jaydens Problem has
