Hi Kalle,

We have a patch for a similar problem. Can you wait for the
verification by Philippe?
Commit 602cc0c9618a81 ("mt76: mt7921e: fix possible probe failure after
reboot")
Link: 
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/net/wireless/mediatek/mt76?id=602cc0c9618a819ab00ea3c9400742a0ca318380

I can reproduce the problem in my v5.16-rc5 desktop. And the issue can
be fixed when the patch applied.


Hi Philippe,

Can you please help to check the patch in your platform?
