Help! RTL8723BS "coalesce failed with error -22" after upgrade

Hey everyone,

I recently upgraded my system, and now I’m having a strange issue with my WiFi (Realtek RTL8723BS).

now I can no longer connect to any WiFi networks as a client. however, creating an Access Point (AP) still works fine, but whenever I try to connect to an existing network, the connection fails.

dmesg logs:
Every time I attempt a connection, dmesg gets spammed with this error:

[ 1083.925640] rtl8723bs mmc0:0001:1 wlan0: xmit_xmitframes: coalesce failed with error -22
[ 1084.921217] rtl8723bs mmc0:0001:1 wlan0: xmit_xmitframes: coalesce failed with error -22
[ 1085.921434] rtl8723bs mmc0:0001:1 wlan0: xmit_xmitframes: coalesce failed with error -22
[ 1086.922320] rtl8723bs mmc0:0001:1 wlan0: xmit_xmitframes: coalesce failed with error -22
....

Has anyone encountered this specific "coalesce" error with the rtl8723bs driver? I'm looking for advice on whether this is a known bug in recent kernels or if there's a specific module parameter I should try to bypass this.

System Info:

• Chipset: RTL8723BS (SDIO)

• Kernel version: 7.0.3-zen1-2-zen
