Subject: [PATCH] powerpc/eeh: Dump PHB3 diag-data on frozen PE
Date: Wed, 20 Nov 2013 17:36:36 +0800	[thread overview]
Message-ID: <1384940196-32514-1-git-send-email-shangw@linux.vnet.ibm.com> (raw)

While we detect frozen PE on PHB3, it's always meaningful to have
the dumped diag-data for further diagnosis and analysis.
