Title:
Kernel modules missing in 5.4.0-37
Status in linux package in Ubuntu:
Incomplete
Bug 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
