Hi,
I'm getting random failures at boot time while loading modules with
kernel 5.x. I'm dual-booting LTS 4.x kernel (4.19.152 at the moment)
and never had any issue with the latter.
Are you experiencing similar problems? I can provide complete dmesg
outputs if helpful but here are excerpts showing the kind of bugs I'm
currently facing (various kernels or kernel configurations):
