WebbIt seems like the behavior wouldn't be any better by giving the HAL timebase its own interrupt, however. It's true that the RTOS tick ISR will be delayed by the HAL code when returning to the task it has selected to run, but using two ISRs the task is going to have to wait for the HAL timer interrupt latency in addtion to the code it calls.
