From 4b063765107ff88ff996c86d6e4ea868df58fec2 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Sun, 9 May 2010 19:15:16 +0300 Subject: pci: irq_state vmstate breakage Code for saving irq_state got vm_state macros wrong, passing in the wrong parameter. As a result, we both saved a wrong value and restored it to a wrong offset. This leads to device and bus irq counts getting out of sync, which in turn leads to interrupts getting lost or never cleared, such as https://bugzilla.redhat.com/show_bug.cgi?id=588133 Signed-off-by: Michael S.
