Thanks for the logs, which you met two kinds of problems. One is firmware gets wrong during system resumes, and the other is to close a disappear netdev. However I still can't dig why it gets wrong. I will focus on latter one first. The behavior between no commit [1] and the latest tree + [2] is the time waiting for ACK from scan abort firmware command. The former one is longer, and latter one is shorter. I also enable kernel debug KASAN suggested by Johannes to dig problem, but in my side I can't see any kernel warning and the crash. Since I saw 'NetworkManager' and 'hostapd' in code trace, I would like to know if you have two virtual interfaces, which for STA and AP modes? (Please check this by 'iw dev') If so, is it possible to remove hostapd (AP mode) to see if this is a factor causing crash. Attachment is a debug patch that add more messages and code trace, please help to reproduce problem with patches of [2] and attachment. If your kernel enables dynamic debug, need additional commands to have debug message: sudo bash -c 'echo -n "module rtw89_core +p" > /sys/kernel/debug/dynamic_debug/control' sudo bash -c 'echo -n "module rtw89_pci +p" > /sys/kernel/debug/dynamic_debug/control' Since there are more than one symptoms causing system freeze, please collect four logs as before. Also please give me two logs that system can normally suspend/resume, so I can compare their difference.
