Db845c freezes on reboot

Hi everyone,

I am not sure if the problem has already been discussed, but sometimes my db845c freezes during a reboot.

I don’t know how to properly fix this, but reverting the commit “tty: serial: qcom_geni_serial: Fix softlock” (a1fee899e5bed457afc20a6a2ff3915a95cc5942) seems to fix the issue.

If this helps: https://pastebin.com/raw/vTrAQFXA



Thanks for reporting this, which path leads you to revert this specific commit? did you perform some debug or bisect?

see https://bugs.96boards.org/show_bug.cgi?id=844

I used git bisect and I had to rebase the necessary patches all along. Long, painful but fruitful.
I am not sure what’s wrong with the commit. The revert side was also annoying.
