From a3b62f2330fbe26d0a4b34b3dac8360bdeb5453e Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 22 Jul 2026 08:25:59 +0000 Subject: [PATCH] wifi: mt76: mt7996: set MT76_MCU_RESET before waking MCU waiters on full reset mt7996_mac_full_reset() called wake_up(&dev->mt76.mcu.wait) without first setting MT76_MCU_RESET. The MCU response wait condition only checks the response queue and that bit, so the wake-up released nobody: a thread blocked in an MCU command against the dead firmware (typically holding dev->mt76.mutex) stayed asleep until its multi-second timeout, stalling recovery. Set the bit before the wake-up, as mt7915 does.
