Bug description:
Hello!
I found that both of generic and snapdragon kernels from focal
repository (5.4.0-14-generic and 5.4.0-14-snapdragon was tested) does
not boot on Lenovo Yoga C630 WOS. Boot process hang at "Loading device
tree blob..." (which means I can not provide apport report, because I
can not boot kernel from focal repository, and apport refuse to
collect information with other kernels).
At the same time snapdragon kernel from https://kernel.ubuntu.com
/~kernel-ppa/mainline/v5.4.20/ boot mostly fine (albeit with
https://bugzilla.kernel.org/show_bug.cgi?id=204685 and
https://bugs.launchpad.net/bugs/1863761 ).
