I do not had Ext4 issues with Kernel 4.19, but I did not want to take
any risks either.

What is the best option to downgrade the Kernel to 4.18 or lower?

I downgraded to Kernel 4.18 on my computers which use Tumbleweed (Kernel
4.18.5) or Leap 15.0 with Kernel_stable repo (Kernel 4.18.6) to a
self-compiled Kernel 4.18.20.

Unfortunately the scripts in package nvidia-gfxG05-kmp-default (Nvidia
driver) do not work with self-compiled kernels. So I also had to
re-compile the Nvidia driver manually. This is not an issue, if you use
the Nvidia *run.sh driver download.

See the Bugzilla discussion. You can simply disable the MQ scheduler
with a kernel boot parameter and avoid the issue.


Which does not work for resolving the issue according to the discussion:
https://bugzilla.kernel.org/show_bug.cgi?id=201685#c54

Nonetheless, a problem in blk-mq was identified. So the cases when
disabling mq did not work must be a different issue or error in
applying the workaround.

Thanks
