@Hui Wang, Having tested it a couple of times now, it is somewhat intermittent. Without the kernel parameter (#23) set though, more times than not the machine will freeze on wake from sleep. It is a Dell 7591 2in1. I know of others with relatively new machines who have had issues with DMICs not being recognised but their solutions have not resolved the problem on this particular model. I have attached a new dmesg, in case it's helpful.
