FreeBSD/src a81a290 (r328278) — sys/powerpc/powernv opal_pci.c
PowerNV: send MSI_EOI always after MSI unmask MSI/MSI-x interrupts are edge-triggered. If an interrupt arrives when IRQ line is masked, it will be lost and will never recover. Perform MSI_EOI always after unmask to give a chance for PHB/XICS to send an interrupt again if MSI/MSI-x pending bit is set in MSI/MSI-x BAR space.
