Bug Description

Hi,

On my lenovo T430 i installed the linux-oem-22.04 to test out 5.17 kernel, to see if it solved the issue regarding intel AX210/AX211 suspend wake-up issue.
I also tried my micro RTL8188 based usb wifi adapter, but it fails to initialize.
It works fine on the ubuntu stock 5.15 kernel (and windows)

On
$ uname -a
Linux T430-i7 5.17.0-1015-oem #16-Ubuntu SMP PREEMPT Mon Aug 8 19:09:19 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

loaded r8188eu module manual to set one-time debug options:
sudo modprobe r8188eu debug=9

dmesg shows:

I think this is a generic 5.17 kernel issue, not sure if it was fixed in later versions
closest info and hint to issue/solution on this issue i found on:
https://bbs.archlinux.org/viewtopic.php?id=277432

With a kernel module signed set as requirement and without having the actual keys where modules are signed with i can't really test the most upstream module version of git.

Small addition:

perhaps not clear from above:
The most visable issue, no wireless interface shows up , neither with ifconfig -a, nor with iwconfig (for rtl8188eu on 5.17 oem kernel)
