Public bug reported: I would like to use a Wi-Fi card supported by the r8188eu kernel module in the initramfs, in Ubuntu 20.04. I add the module using a custom initramfs-tools hook. My problem is that there is a difference in the firmware dependencies of the module between the standard 5.4 kernel and the current HWE 5.15 kernel: in 5.4, the module depends on /lib/firmware/rtlwifi/rtl8188eufw.bin, while in 5.15 it no longer does so. You can verify it using `modinfo -F firmware r8188eu` (perhaps with the `-k` parameter if you do not want to check the currently run kernel).
The card requires the mentioned firmware file. In order to use it with both kernels, in addition to `manual_add_modules r8188eu`, I have to put something like `copy_file firmware /lib/firmware/rtlwifi/rtl8188eufw.bin` in my initramfs-tools hook. The bug is fixed (https://lore.kernel.org/lkml/YulcdKfhA8dPQ78s@nx64de- df6d00/) in Linux 5.15.66 (https://lwn.net/Articles/907524/). Please consider backporting the fix or updating the HWE kernel package to 5.15.66. ** Affects: linux-meta-hwe-5.15 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-meta-hwe-5.15 in Ubuntu. https://bugs.launchpad.net/bugs/1989162 Title: The r8188eu kernel module does not depend on the rtlwifi/rtl8188eufw.bin firmware file in the 20.04 HWE kernel Status in linux-meta-hwe-5.15 package in Ubuntu: New Bug description: I would like to use a Wi-Fi card supported by the r8188eu kernel module in the initramfs, in Ubuntu 20.04.
