Subject: mce: Add errata workaround for Skylake SKX37
Date: Fri, 29 Oct 2021 16:57:59 -0400 [thread overview]
Message-ID: <20211029205759.GA7385@codemonkey.org.uk> (raw)
Errata SKX37 is word-for-word identical to the other errata listed in
this workaround. I happened to notice this after investigating a CMCI
storm on a Skylake host. While I can't confirm this was the root cause,
spurious corrected errors does sound like a likely suspect.
