Dear Ping-Ke Shih,
I am encountering an unpredictable bug with the Realtek rtw89 wireless
driver (rtw89_8922ae) on my system. Sometimes, especially when
downloading files or under heavier network load, my system slows down
significantly and eventually hangs.
In the kernel log (dmesg), I observe repeated lines like these looping
continuously:
Nov 27 18:06:22 desktop kernel: rtw89_8922ae 0000:07:00.0: no tx fwcmd
resource
Nov 27 18:06:22 desktop kernel: rtw89_8922ae 0000:07:00.0: failed to
send h2c
I have attached a snippet of the dmesg log that includes these and other
relevant lines for your reference, along with the output of the
ver_linux script and some more potentially useful information.
I'm running on kernel release "6.17.8-arch1-1", and this is the wireless
NIC in my motherboard:
07:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd.
RTL8922AE 802.11be PCIe Wireless Network Adapter [10ec:8922] (rev 01)
Subsystem: Realtek Semiconductor Co., Ltd. RTL8922AE 802.11be
PCIe Wireless Network Adapter [10ec:8922]
Kernel driver in use: rtw89_8922ae
Kernel modules: rtw89_8922a
Please let me know if you need any additional information or if I can
help test potential fixes.
Thank you for your attention,
Orel Lazri

How heavy is the network load?
"system slows down" means whole system become lag? Or network slows?
"hangs" refers to network (WiFi)? or system?

Normally, this is because of firmware stopped.

Some questions and actions:
1. What's the firmware version you are using?
(see kernel log when it probes RTL8922AE)
2. The attachment shows that SER happened. That means hardware or firmware
gets abnormal. Please collect more instants for us.
3. Turning off WiFi power save could help?
sudo iw wlan0 set power_save off
4. Turning off ASPM follows Larry's README [1].
