Error description
In TX/RX macros for component tracing , driver uses tx_lock/ slih_lock for synchronization between threads trying to write to TX/RX component trace. Since tx_lock/slih_lock are obtained with interrupts disabled to driver interrupt priority, we have to make sure we raise the interrupt priority to driver interrupt priority for every component trace write. Absence of this logic caused system crash in ct_hook5.
