Hmm, this look like a serial driver problem. Which of course is just
as serious, but relieving for me as I had no idea where to start
looking in qmi_wwan or cdc_wdm.
Could you do a quick verification: please test if the problem
disappear if you blacklist your serial driver (option?). If so,
then I hope someone else can look into it. I seem to vaguely
remember a similar report, but cannot find it right now.

OK, that is good. There cannot be that many changes after
that.
