Please add me to Cc as I am not on the list.

You probably need to get latest firmware from https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git
and splat the intel related firmware into /lib/firmware/

Did that, but still the same issue...

Removing /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm fixed this issue.

Found more info on Gentoo bugs: https://bugs.gentoo.org/777324#c6
So either commit 000735e5dbbb739ca3742413858c1d9cac899e10 should be
ported to 5.11-stable or PNVM loading disabled.

Unfortunately we can't just backport the FW version bump.  There are
actual API changes that need to be supported, so that would require an
unfeasible amount of changes for a stable tree.

We have two options:

1. Try to take a fix to the -59.ucode firmware (I'll take this
internally)

2. Prevent the driver from loading the PNVM file when older firmwares
are used (I'll check if there is a proper way to do this without
relying on the actual version number).
