Fixed In Version: kernel-rt-3.10.0-693.11.1.rt56.631.el7
Doc Type: Bug Fix
Doc Text:
In the realtime kernel, if the rt_mutex locking mechanism was taken in the interrupt context, the normal priority inheritance protocol incorrectly identified a deadlock, and a kernel panic occurred. This update reverts the patch that added rt_mutex in the interrupt context, and the kernel no longer panics due to this behavior.
