Hi all,

I still have som issues from time-to-time with the LM842 dongle in my i.MX6 SoloX board. So I started to play around with the firware dump mechanism that Ping-Ke Shih sent up in https://lore.kernel.org/linux-wireless/20231016053554.744180-1-pkshih@realtek.com/T/#t . Here are some dumps that I recieved, please let me know if you can make something out of these dumps and also if you want me to test something else, since I have a fairly easy way to make the driver stall.

BR Petter

First example is from "firmware failed to leave lps state"

```

Second crash is when I tried to extend the driver with a firmware dump, when I got stuck in "failed to get tx report from firmware" (since this is the most common place the driver stalls for me). However it seems like I got some lock dep issue while doing it, but hopefully the below firmware dump can show something interesting at least..

I used:
