Subject: arm64: perf test 26 rpi4 oops
Date: Fri, 28 Jul 2023 06:06:33 +0200 [thread overview]
Message-ID: <b39c62d29a431b023e98959578ba87e96af0e030.camel@gmx.de> (raw)
perf test 26 in virgin master inspired the below.
The oops is not brand new, apparently arriving sometime after 6.1, as
the stock 6.1.21 Raspian/PiOS kernel does not reproduce but the rpi-
6.4.y pi kernel (https://github.com/raspberrypi/linux.git) branch does.
