Hi Marex,

We backported this patch to ubuntu 4.15.0-generic kernel, and found this patch introduced the rsi driver crashing when running system resume on the Dell 300x IoT platform (100% rate). Below is the log, After seeing this log, the rsi wifi can't work anymore, need to run 'rmmod rsi_sdio;modprobe rsi_sdio" to make it work again.

So do you know what is missing apart from this patch or this patch is not suitable for 4.15 kernel at all?

Does 4.19.191 work for this system? Why not just use that or newer instead?

thanks,
