[SB2] mwifiex_pcie intermittently timeout and hang on when `modprobe -r` or rebooting system
Issue
mwifiex_pcie intermittently timeout and hang on when modprobe -r or rebooting system. When issue happens, I have no way to recover but a hard reboot.
The dmesg log when issue happens is as below:

I have the similar issue using Manjaro. When the pressure on wifi is high (torrents, for example), mwifiex_pcie crashes immediately and wifi stops working. Only reboot can make it work again. Also it might happen after waking up from lockscreen or randomly at all.
Same issue on manjaro. Happened for all versions of 5.3.18, but didn't happen on 5.4.6-1. I upgraded to 5.5.3-1 yesterday and have had mwifiex_pcie crash again (when torrenting). Does seem to only happen when pressure is "high" for me. On restart I usually have to do a hard reboot as just rebooting times out and then stops, though I haven't investigated why yet.
