cool thanks, it seems to be an issue with the linux kernel, but im wondering if a possible workaround in nixos is to select a different firmware module.
Background, this is a headless DSLR camera controller using a Kangaroo PC from a few years ago (Intel(R) Atom(TM) x5-Z8500)
My issue is interesting because im getting this kernel error whenever I try to trigger a DSLR with gphoto2:
Oct 17 00:23:03 leafcam1 kernel: cht-bsw-rt5672 cht-bsw-rt5672: ASoC: failed to init link SSP2-Codec: -517
Oct 17 00:23:03 leafcam1 kernel: cht-bsw-rt5672 cht-bsw-rt5672: snd_soc_register_card failed -517

Whats weird is that this firmware module is used for audio if im not mistaken
Back in 2017 hopkinskong wrote a linux_cherrytrail customized linux kernel here that may be of help

Im having continued issues regarding reliability with gphoto and the DSLR im using and im wondering if it would be related. Im assuming no but seeing kernel errors make me want to clean them up regardless
