When I attempt to boot my 5.10rc2 kernel with that memmap option, my
machine immediately hangs.  That said, it seems to have done something
bizarre, as immediately afterwards, if I remove that option and let
5.10 boot normally, it seems to boot and bring up the wifi adapter ok
(which didn't happen before).  Now that I've managed to boot 5.10
twice, the first time after a couple of minutes my video started going
nuts and displaying all sorts of artifacts[1].  This time things seem
to be functioning nominally (wifi is online and the machine is
behaving properly).  I may just never turn it off again :D.
