Hello, After upgrading to 4.18rc1 iwlwifi is printing a FW error. There was a previous thread with a similar issue but they seemed to resolve it with a ucode update. I think I'm running a newer FW and am still having an issue. 4.13 works--I haven't gone any higher so far. iwlwifi 0000:02:00.0: Microcode SW error detected.
