Among the affected boards are = ones manufactured by TX-Team, so the Duo Box might be affected as well, but I have no spare sys= tem to verify that. Not being an expert at all when it comes to USB troubleshooting, I am not sur= e yet if we are dealing with two distinct issues or just one. The following patches seem = to be related: - https://lore.kernel.org/stable/20211126122340.1193239-2-mathias.nyman(a)lin= ux.intel.com/ - https://lore.kernel.org/all/20211220143044.382652365(a)linuxfoundation.org/ Both should be included in kernel 5.15.11, released 2021-12-22. With 22.79% of all reporting Fireinfo profiles running on Core Update 162, an= d 21.99% running kernel 5.15.6 (the rest apparently did not reboot after upgrading their syste= m), the overall userbase affected by this/these issue(s) is low. However, depending on the network setup, affected systems might be completely= unreachable after upgrading (if the USB networking device serves for RED interface), requiring = physical presence to downgrade them or swap NICs. Therefore, I think it makes sense to ship the= latest 5.15.x kernel as soon as possible. Any thoughts on this? Does anyone have more detailed information, especially = if there are no obvious messages in /var/log/bootlog and similar? Thanks, and best regards, Peter M=C3=BCller --===============6389056187902825216==--
