Hi folks. During Wi-Fi operation, the following entry in the kernel logs was noticed: Microcode SW error detected. Restarting 0x0.

Take this opportunity I wanna ask is it normal that kernel logs flooded with such messages: authenticate with 50:ff:20:04:c8:dc send auth to 50:ff:20:04:c8:dc (try 1/3) authenticated associate with 50:ff:20:04:c8:dc (try 1/3) RX AssocResp from 50:ff:20:04:c8:dc (capab=0x1811 status=53 aid=1) 50:ff:20:04:c8:dc denied association (code=53) authenticate with 50:ff:20:04:c8:dc send auth to 50:ff:20:04:c8:dc (try 1/3) authenticate with 50:ff:20:04:c8:dc send auth to 50:ff:20:04:c8:dc (try 1/3) authenticated associate with 50:ff:20:04:c8:dc (try 1/3) RX AssocResp from 50:ff:20:04:c8:dc (capab=0x1811 status=0 aid=1) associated Thanks. -- Best Regards, Mike Gavrilov.
