Subject: Oops on mcp251xfd open on 6.6.52
Date: Mon, 23 Sep 2024 13:53:10 +0200 [thread overview]
Message-ID: <20240923115310.GA138774@francesco-nb> (raw)
Hello,
I got the following Oops on doing a simple ip link set canX up, running
on an i.MX8MM SoC.
This was reproduced with some automated testing, I have not tried to
reproduce it so far. Any idea or hint? It seems systematic, introduced
around 12th september on the v6.6.y branch.
