Subject: Non systematic PCIe error on resume on i.MX8QP on Linux 7.2
Date: Mon, 20 Jul 2026 07:27:42 +0200 [thread overview]
Message-ID: <20260720052742.GA6753@francesco-nb> (raw)
Hello,
our CI spotted this error on resume. It is not systematic, and it is
possible that this is not a new issue from 7.2.
Does it rings any bell?
