 Hi,
 
 I am using in a daily basis iwm0 driver with this device in my thinkpad 
 x260:
 
 [     1,013793] iwm0 at pci2 dev 0 function 0: Intel Dual Band Wireless 
 AC 8260 (rev. 0x3a)
 
 The only problem I found is that sometimes it takes long time to connect 
 to the router but once it connects it works "well", slow but stable.

 Also remember some iwm firmware errors after "shutdown -p now" (I cannot 
 find them in the logs)
