I spoke too soon. The crashes are indeed gone, but hanging smbd is still
very real. This seems to happen most on domain joins over wifi. I am not
quite sure how to capture this. Any suggestions on how to get logs or
what not would be appreciated. I am not seeing anything that shows it
that I recognize quickly except for two backtraces (which are with
beta2-GIT-9afd4be). One is the right time frame, another is not:
