commit c0af1d7386ec67c97950fbd873354dfc20a23a34 Author: raiden00pl <[email protected]> AuthorDate: Thu Oct 22 18:18:05 2026 +0200 arch/arm/nrf52,nrf53,nrf54l: do not raise the IEEE 802.15.4 interrupt priority The RADIO, TIMER and RTC interrupts ran at NVIC priority 0, above the critical sections, while their handlers call the OS. Leave them at the default priority.
