Subject: unhandlable pages
Date: Mon, 21 Mar 2022 10:17:29 -0700	[thread overview]
Message-ID: <YjizKd4scejFi6fl@agluck-desk3.sc.intel.com> (raw)

Validation folks are seeing this on a v5.16 kernel. I don't
see any changes in v5.17 that look like they address it.

Mar 04 14:05:05 JF5300-07B181T kernel: Memory failure: 0x195cda44: recovery action for unknown page: Ignored

Som debugging shows this is an anon page (expected ... that's the
type of page where the error was injected. They see shake_page()
called three times, but it doesn't change anything, so the page
is reported as unhandlable.
