[question] e1000 interrupt storm happened because of its corresponding ioapic->irr bit always set

["Zhang Haoyu" <zhanghy@xxxxxxxxxxx>]

Hi, all

I use a qemu-1.4.1/qemu-2.0.0 to run win7 guest, and encounter e1000 NIC interrupt storm, 
because "if (!ent->fields.mask && (ioapic->irr & (1 << i)))" is always true in __kvm_ioapic_update_eoi().

Any ideas?

Thanks,
Zhang Haoyu
