5.15.0-69 breaks my wifi

[Andreas Stiller]

Latest linux kernel completely kills my Wifi. Have had to use the GRUB boot loader to revert the kernel back twice.

wlan devices are recognized, but they cannot find any network. Reinstall of device driver did not help.

Revert to Kernel 5.15.0-67 brings wlan back.

Note, the internal intel wlan device has no antenna connected. It is probably working. The broadcom wlan device has an antenna connected and stopped working.

[Gniewomir Świechowski (gniewomir-swiechowski)]

Same problem, 67 -> wifi works, 69 -> wifi disapears.

wireless card is ASUS PCE-AC88

Some digging supports theory that patch was backported to kernel 5.15.0-69 which treats valid value as faulty/indication of error therefore preventing loading of module:

[ 2740.647600] brcmfmac 0000:0d:00.0: brcmf_pcie_init_ringbuffers: invalid
> max_flowrings(264).

please do handle this as duplicate as the bug 2013186 stays in state unconfirmed because of missing log files.
