I can confirm that this bug also affects my system. My experience provides a new, critical piece of information that may help with the diagnosis.
Laptop Model: Dell G15 5511 Wi-Fi Module: Intel Tiger Lake PCH CNVi WiFi [8086:43f0] Working Kernels: 6.14.0-23-generic, 6.14.0-24-generic Non-working Kernel: 6.14.0-27-generic Critical Observation: Power State Dependency I discovered that the bug is directly related to the laptop's power state during boot. When I start the laptop with the AC charger plugged in, the Wi-Fi card and other devices fail to be detected. When I start the laptop on battery power, the Wi-Fi card works as expected. This suggests a regression in the kernel's power management for the PCIe bus when the system is operating on AC power. The dmesg output from a failed boot shows a specific timeout error related to the Wi-Fi card's firmware initialization: 00:14.3 failed to run init ucode: -110 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2119152 Title: Kernel 6.14.0-27-generic regression on Samsung 960XGL: touchpad, wifi, USB keyboard fail To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-6.14/+bug/2119152/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
