git checkout 415f12efc1b2308411b2cbc3e82666b3db8a7758^

[build, confirm it works, grab logs]

git checkout 415f12efc1b2308411b2cbc3e82666b3db8a7758

[build, confirm it's broken, grab logs]

It's not the sort of change that's really revertable...

Thanks again. I confirm that Bugzilla 83550 is the same issue. I have attached
the captured logs
there for reference.

"scrollback" buffer (I assume you have oodles of RAM). Or grab the
kernel logs from your system.
