From a7fb7ea76e20740c641a9b5401ef45b3b022cb69 Mon Sep 17 00:00:00 2001 From: Linas Vepstas Date: Fri, 10 Aug 2007 09:27:00 +1000 Subject: [POWERPC] pseries: device node status can be "ok" or "okay" It seems that some versions of firmware will report a device node status as the string "okay". As we are not expecting this string, the device node will be ignored by the EEH subsystem. Which means EEH will not be enabled. When EEH is not enabled, PCI errors will be converted into Machine Check exceptions, and we'll have a very unhappy system.
