@gsora @mntmn Indeed that RK3588 crushes the only other ARM laptop I have tried (the RK3588 based Pinebook Pro, granted also in a different price bracket)

Also you probably would have notices noise on the 5V line when you probed it (and why only during startup?)

I'm not having high hopes though, it is powered from 3V3 which is PG before 1V35 and then VDD.
Also with a 100k mode VDD should take ages to soft start (1.4ms) and the lin reg only takes 0.1ms and has a head start -
talpa (talpa@fosstodon.org)'s status on Thursday, 12-Oct-2023 00:19:02 JST talpa @abortretryfail @mntmn I was wondering if the module required some sort of power sequencing, and if the timing was marginal.
