It just causes a constant rate of 5000 interrupts per second for both

What WiFi chip/module does this use? It might be worth asking Broadcom
people to help with this and fix the driver.
Based on the comments in the device tree file, it uses an AP6210, which
is a BCM43362 inside for SDIO-based WiFi. There is a recent fix in 5.6-rc1
for this,
8c8e60fb86a9 brcmfmac: sdio: Fix OOB interrupt initialization on brcm43362
which seems to fix things for me. Could you try it on your end?
I can confirm that it works as you say (on linus/master). 5.5 still doesn't
have
the patch, so it's broken there, which confused me I guess.
Hi Ondrej,
I have seen emails from GregKH including this patch in 5.5 stable so it
will also land there eventually.
Regards,
Arend
Please ignore this patch.
thank you,
Ondrej
