Subject: Regression with mainline kernel on rpi4
Date: Thu, 2 Sep 2021 10:08:19 +0100	[thread overview]
Message-ID: <CADVatmPB9-oKd=ypvj25UYysVo6EZhQ6bCM7EvztQBMyiZfAyw@mail.gmail.com> (raw)

Hi All,

Our last night's test on rpi4 had a nasty trace. The test was with
7c636d4d20f8 ("Merge tag 'dt-5.15' of
git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc"). Previous test
was on 9e9fb7655ed5 ("Merge tag 'net-next-5.15' of
git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next") and it
did not have this trace.
