With v5.13-rc2, I've been seeing an odd boot regression with the
DragonBoard 845c:

Unfortunately, trying to bisect it down (v5.13-rc1 works ok) is giving
me inconsistent results so far. It feels a bit like maybe some config
option gets enabled moving forward, and then sticks around when we go
back. I'll take another swing at bisecting it later today, but I have
to move on to some other work right now, so I figured I'd share (with
folks who better know the recent __apply_alternatives changes) in case
folks have a better idea:

Please can you try reverting af44068c581c and 0c6c2d3615ef?

Thanks,

I saw a crash yesterday evening on my Huawei D05 and D06, but it went away with a clean build...

Here's my draft mail:

I just noticed this this evening on my Huawei D06 and did not see same or similar reported elsewhere:
