From fb48dc22824daaa60ff1d6a6c9e22c79112dfb8e Mon Sep 17 00:00:00 2001 From: Brian King Date: Mon, 25 Nov 2013 16:27:54 -0600 Subject: [PATCH] powerpc: Increase EEH recovery timeout for SR-IOV In order to support concurrent adapter firmware download to SR-IOV adapters on pSeries, each VF will see an EEH event where the slot will remain in the unavailable state for the duration of the adapter firmware update, which can take as long as 5 minutes. Extend the EEH recovery timeout to account for this.
