Master regression - boot loop due to kernel panic on latest snapshot (mt7621/Archer C6 v3)

For Developers
21

As you can see, this second branch is based on openwrt-21.02.
If you check its log, you would see its just after the 21.02.2 release! :+1:

Just fetch my branch from my fork into your working copy as a local branch, checkout and build it as usual.

I could provide the git commands later, if you need it. :slightly_smiling_face:

Here you are, @dsouza

# go to your local clone
$ cd openwrt

# add my fork to your working copy and name it e.g. "xabolcs-github"
$ git remote add xabolcs-github https://github.com/xabolcs/openwrt.git

Thank you @xabolcs for the instructions! Test done and passed (r0+16499-855f60e85e)!

Since my device (Archer C6 v3.2) is not yet supported in 21.02, I built and tested with an image of Archer A6 v3, which has the same hardware.

Boot is OK, test passed (rebooted it 5 times, all boots completed sucessfully)!

BTW, how do I update github with "Tested by"? My user there is "d-me3".

Thank you for verification!
I'll handle commit update! :wink:

If you don't mind revealing your real name and email address, then just provide the information here, as a comment:

Tested-by: Your Realname <valid@email.adress>

Of course I could use @dsouza on OpenWrt Forum otherwise.
