My GeForce GTX 1660 Ti mobile (NV168/TU116) in Hyperbook NH5/C=
levo NH55RCQ
worked "fine" with some applied workarounds with kernel 5.2
(https://bugs.freedesktop.org/show_=
bug.cgi?id=3D110830#c14), however, with
upgrade to 5.3 it started to hang video on the NVidia card state switch. In
fact, I don't use it to render the output (is DynOff by default), but I can=
not
disable it in BIOS and when I open/close a laptop lid it is temporarily wak=
en
up to get back to sleep after a few seconds. It works that way in 5.2, but =
in
5.3 it "hangs video" on the consequtive switch (occasionally also=
during the
first X/gdm setup).
The key related errors in the system log:

On boot (here with self rebuilt kernel-core-5.4.0-0.rc6.git0.1.fc30.x86_64 =
on
Fedora 30, but the errors are similar with 5.3) I see:

I've seen similar issue, however, in that case it is a regression - it work=
ed
fine with kernel 5.2 (tested since RC1 to 5.2.18) and it's broken in 5.3
(tested with 5.3.1 to 5.3.8 and 5.4.0-rc6).
I'm not sure which commit broke it (building the kernel takes some time), b=
ut
having some candidates I could try to verify before/after it occurs or not.
Btw, I'm looking for potential workarounds (better than sticking to 5.2.18)=
. I
don't use NVidia to render the output, so I could blacklist nouveau and use
bbswitch to keep NVidia card off. However, it would make testing newer kern=
el
versions somehow harder. Maybe I can disable something in nouveau to keep t=
he
card off and still do not suffer from the errors above?
