SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly from a mainline/stable Linux tree or
a minimally backported form of that patch. The following upstream
stable patches should be included in the Ubuntu kernel:

Linux 5.8.18
UBUNTU: upstream stable to v5.8.18
I'm sorry if this is the wrong place to ask, but there is a bug, that makes systems with Intel cpu with eDRAM unbootable. This bug is already fixed upstream. 5.8 is EOL, so it will never get the fix. Can the fix be backported to groovy's 5.8 kernel, or it has to wait for the next Ubuntu version? https:/
