Subject: very long boot times in 5.13 stable.
Date: Tue, 27 Jul 2021 09:10:11 -0700	[thread overview]
Message-ID: <aeac0ff3-6606-3752-db6c-306a9c643f8f@candelatech.com> (raw)

Hello,

My system was stable with 5.13.0, though there was a KASAN warning.
So, I upgrade to 5.13.5, and now it takes a very long time to fully boot to
login prompt, and I see this splat in the logs.

I'm working on bisecting, but if someone has a clue, please let me know.
