Hi Frederic, <snip>
Sorry for the lag, I still don't understand how this specific commitcan produce this issue. Can you please retry with and without this commitreverted?
Just tested v6.12-rc6 with and without the revert. Without the revert, the touchpad and the wireless adapter both stopped working, whereas with the revert, both devices functions as normal.
I have attached the dmesg for both kernels below. Unlike the log we got last time, there is no direct reference to tg3 any more, but the NMI backtrace still pointed to NetworkManager and net/netlink-related functions (perhaps a debug kernel would be more helpful?). Here's a snippet:
