From 0e17b560985afb5190e859d5d4609237a91bb732 Mon Sep 17 00:00:00 2001 From: John Keller Date: Wed, 2 May 2007 09:09:18 -0500 Subject: [IA64] - Altix: hotplug after intr redirect can crash system When redirecting a device interrupt on SN, not all links between platform specific structures are being updated. This can result in a system crash if an interrupt redirection is followed by an unplug of that device. The complete fix also requires a prom update. Though, this patch is backward compatable and not dependent on the prom patch.
