Comment 8 for bug 1776443

I installed the latest upstream kernel, headers and modules. As far as I can tell, it suffers exactly the same failure as the latest released bionic lowlatency kernel. The stack ttrace seems very similar and the timeout message looks to be the same. My guess is still the intel iwlwifi version 29 firmware (although all the older versions which will load onto my 3165 wifi adapter have failed in similar but not identical ways).

I will attach a couple of journalctl logs for anyone interested and knowledgeable enough to compare.
