Builds have not been working on the Netgear R6220 for some time. Reference the following threads:
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=337924
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=337074

Serial logs were requested to help troubleshoot this issue. The requested log is attached, capturing the bootloop behavior after installing r58976.

Please let me know if additional data captures are required, or if I can provide additional troubleshooting assistance.

There's obviously something askew with the R6220 (and whichever similar devices) since there's not an issue with the R7450, apparently (screenshot in eBay listing): FS: NETGEAR Nighthawk R7450 flashed with latest DD-WRT. Forwarding log and link to this thread in my email thread reply to BrainSlayer.

Many thanks!

Yikes--my apologies. Not sure what happened there. I was watching the serial data via PuTTY as it rebooted and it was definitely readable, but I stupidly did not check the log before I posted it. Not sure why it looks different than what I saw on the screen.

Here is another log (that I checked) that shows the same behavior, but for an earlier build (r51154).

It's interesting because the log file "R6220_bootloop_r58976.txt" I downloaded and emailed was readable and showed 3 kernel panics:

I downloaded the first file post too and it was totally readable. Weird!

[MysticCobra]

OK, I'm crazy now too, because after I read BrainSlayer's post this morning, I tried to open the file on my laptop, and it was garbage.

So apparently, it's a Schroedinger's Cat situation: It's both garbage _and_ readable, until you open it and collapse the waveform into one or the other!

[MysticCobra]

Not that it's important, but I figured out that readability of that file is dependent on which editor I open it in. If I use Notepad, it's garbage. If I use Notepad++, WordPad, or Word, it's readable.

But I still don't know why that happens. ¯\_(ツ)_/¯

[kernel-panic69]

That's funny, because you can see exactly what I used to open it (Notepad!)
