Subject: [PATCH] ipmi: set si_trydefaults=0 for ARM64
Date: Mon, 20 Jun 2016 13:26:15 -0500 [thread overview]
Message-ID: <1466447175-14263-1-git-send-email-tcamuso@redhat.com> (raw)
Port I/O space does not exist in ARM64 and is not mapped. Attempts to
access it on ARM systems cause stack traces and worse.
