From bba6f6fc68e74d4572028646f61dd3505a68747e Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 28 Mar 2007 15:36:09 +0200 Subject: [PATCH] MSI-X: fix resume crash So I think the right solution is to simply make pci_enable_device just flip enable bits and move the rest of the work someplace else. However a thorough cleanup is a little extreme for this point in the release cycle, so I think a quick hack that makes the code not stomp the irq when msi irq's are enabled should be the first fix. Then we can later make the code not change the irqs at all. Signed-off-by: Eric W.
