 |

Hello,
| Code: | uname -a
Linux lnx 5.4.38-gentoo #2 SMP Thu Jul 2 08:11:47 EEST 2020 x86_64 Intel(R) Atom(TM) CPU D510 @ 1.66GHz GenuineIntel GNU/Linux |
stable version, with all latest updates (regularly updated with emerge --sync && emerge -Du world)
After kernel upgrade linux-5.4.38-gentoo -> linux-5.4.48-gentoo not working USB wireless device.
Same .config used from linux-5.4.38-gentoo kernel.
| Code: | lsusb:
Bus 001 Device 047: ID 0cf3:7015 Qualcomm Atheros Communications TP-Link TL-WN821N v3 / TL-WN822N v2 802.11n [Atheros AR7010+AR9287] |
all the time repeating messages in dmesg:

Everything works perfect after downgrade to linux-5.4.38-gentoo
How to find the problem cause?
