Hello Coiby Xu (coiby), thanks a lot for this information! Will
definitely try this should I encounter a similar error again; and its
just generally good knowledge. Completely forgot about the initramfs.

Hello Coiby,
I built and installed the module as per the instructions in the branch
you linked me to and `journalctl -k|grep amd_gpio` showed nothing. No
new printouts in the kernel log. So I recompiled the module again with
the pr_alert() statement you printed above and still nothing.
So, I reco
Hello Coiby,
Hmm, as far as I can tell the proper module is being used since I
executed the same steps for both the 5.7.19 and 5.8 kernels. I also
confirmed this by running `modinfo pinctrl_amd` and verifying that it is
no longer signed. I understand what you are saying regarding 0x51bc8,

@Coiby Xu (coiby)
Hello Coiby, had some time today so I compiled 5.7.19 from ubuntu
mainline (https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.7.19/) with
pinctrl_amd configured as a module, applied the patch in #171, and ran
the command you provided:
$ sudo cat /sys/kernel/debug/gpio | grep -A1
@Coiby Xu (coiby)
Yes, that summarizes my findings nicely.

MSFT Touchpad not working on Lenovo Legion-5 15AR
@Coiby Xu (coiby)
It seems that the patch in 171 does not work (i.e. touchpad is still
dead) on kernels older than 5.8. I tried 5.4.75, 5.7.19, and 5.8.18. I
don't really want to look into this further since I'm fine with the
newer kernel, but wanted to give you and any other users a heads up in

Definitely! The attached output was compiled from 5.4.0-52 with the
patch listed in 171.

Hello again, I manually applied both the patches present in #239 and in

I have not (yet) experienced the issue you are describing, or any issues
for that matter. Maybe you can remove and re-insert i2c_hid when this
happens? Hopefully a fix of the GPIO driver is not too far off and will
resolve the stability issues you are experiencing.
