2020-06-12 11:06:47 Ubuntu Kernel Bot linux (Ubuntu): status New Incomplete
2020-06-12 12:58:51 Jean description I recently updated my Ubuntu 20.04 to the latest kernel (5.4.0-37) but upon reboot my Dell XPS lost a few peripherals, like the wifi, and the possibility to use the Dell WD-15 docking station for LAN or external monitors; USB hub functionality was working though. After some inspection, I've found that several kernel modules are missing for that specific kernel version: $ find /usr/lib/modules -iname ath10k /usr/lib/modules/5.4.0-28-generic/kernel/drivers/net/wireless/ath/ath10k /usr/lib/modules/5.4.0-31-generic/kernel/drivers/net/wireless/ath/ath10k /usr/lib/modules/5.4.0-33-generic/kernel/drivers/net/wireless/ath/ath10k And lspci shows the wireless card twice (one more time at the top) and that the following modules and drivers are not loaded for the proper devices: - i915 - processor_thermal_device - intel_pch_thermal - intel_lpss_pci - mei_me - snd_hda_intel - nouveau (but not the nvidia, which I'm using) - ath10k_pci - rtsx_pci Restarting with the previous kernel version (5.4.0-33) works without any issue. I'll attach both lspci outputs, but you can easily review the diff here: https://www.diffchecker.com/mVCbTzSL I recently updated my Ubuntu 20.04 to the latest kernel (5.4.0-37) but upon reboot my Dell XPS lost a few peripherals, like the wifi, and the possibility to use the Dell WD-15 docking station for LAN or external monitors; USB hub functionality was working though.
