Public bug reported:
System experiences kernel panics causing complete lockups when the mt7925e WiFi
driver
attempts to reset after association failures.
Hardware: Framework Desktop (AMD Ryzen AI Max 300 Series)
BIOS: 03.04 (11/19/2025)
WiFi Card: MediaTek MT7925 (RZ717) Wi-Fi 7 at c0:00.0
Firmware: Build Time: 20250721232943
Root Cause:
NULL pointer dereference in mt76_connac_mcu_uni_add_dev() function at offset
0xba
during WiFi MAC reset workflow.
Crash Pattern:
1. WiFi association attempts fail/timeout with AP
2. Driver logs "Message timeout" errors (sequences 6-10)
3. mt7925_mac_reset_work initiated
4. During interface re-initialization via ieee80211_iterate_interfaces
5. mt76_connac_mcu_uni_add_dev attempts to dereference NULL pointer
6. Kernel panic - system completely locks up
Frequency: Multiple crashes per day, making system unusable
This appears to be a known issue affecting multiple users on Ubuntu 25.10
kernel 6.17.0-8 with this hardware.
