The bisect has not provided much more detail. This issue does not appear to be a regression and appears to have always existed.

I was able to get additional debug info and a call trace by enabling CONFIG_DEBUG_PREEMPT, CONFIG_PROVE_LOCKING and CONFIG_JBD2_DEBUG. It also shows a circular locking issue. I will analyze this data for the next steps. I'll post the logs in the next comments.
