Public bug reported:
I am booted into kernel 6.14-36 and networking works fine, but if I boot
into 6.14-37, there is no networking (doesn't see the cable) and WiFi
doesn't work either. The logs are from the working kernel.
$ sudo lspci -knn |grep -iA3 net
01:00.0 Network controller [0280]: Qualcomm Technologies, Inc QCNFA765 Wireless
Network Adapter [17cb:1103] (rev 01)
Subsystem: Foxconn International, Inc. QCNFA765 Wireless Network
Adapter [105b:e0bb]
Kernel driver in use: ath11k_pci
Kernel modules: ath11k_pci
02:00.0 USB controller [0c03]: Renesas Technology Corp. uPD720202 USB 3.0 Host
Controller [1912:0015] (rev 02)
If you want I could boot back into the non-working kernel and make a
file of the dmesg output or something else if that is helpful.
Thanks,
Rob
