The rescan patch is not included in Wheezy irqbalance 1.0.3-3. What is
happening is that your device MSIs aren't being registered before
irqbalance does its initial scan, so it doesn't find them in sysfs.
This rescan patch was designed to allow for recreating the IRQ map after
a hotplug event, such as a CPU or PCI/-X/e card. It also fixes the boot
time IRQ enumeration/irqbalance startup order problem as the 2nd scan
finds the entries in sysfs.
