A lot of modern Clevo barebones have touchpad and/or keyboard issues after
suspend fixable with nomux + reset + noloop + nopnp. Luckily, none of them
have an external PS/2 port so this can safely be set for all of them.

I'm not entirely sure if every device listed really needs all four quirks,
but after testing and production use. No negative effects could be
observed when setting all four.

Setting SERIO_QUIRK_NOMUX or SERIO_QUIRK_RESET_ALWAYS on the Clevo N150CU
and the Clevo NHxxRZQ makes the keyboard very laggy for ~5 seconds after
boot and sometimes also after resume. However both are required for the
keyboard to not fail completely sometimes after boot or resume.

Hmm, the very laggy bit does not sound good. Have you looked into other
solutions, e.g. what happens if you use just nomux without any of the
other 3 options ?

I tried a lot of combinations, but it was some time ago.

iirc: at least nomux and reset are required and both individually cause the lagging.

So the issue is not fixed by just using a different set of quirks.

Hmm, ok. So given that this seems to be the best we can do
the patch looks good to me:

Afaik this patch never got merged. Sadly I still have no better solution, so
I wanted to bring the patch up for discussion again as it still makes the
situation better in my opinion.

Could you rebase on top of the latest kernel?

Thanks.
