Hi Team,

Any updates on this? I can reproduce this hard crash on v5.9-rc1 as well.

It is not a blocker for us because we switched to a userspace
workaround, where we do not wait for modem to shutdown gracefully and
SIGKILL it instead, during the shutdown/reboot process. But I'm happy
to take a swing at any intermediate/in-progress solution available.
