Re: [PATCH] x86, irq: Keep IRQ assignment for PCI devices during suspend/hibernation, bisected

[Borislav Petkov]

Ok,

so I went and looked at tip and which branches could be the usual
suspects. And whaddya know, tip/x86/apic was the first to pick and it
contained the culprit:

6a38fa0e3c94 ("x86, irq, ACPI: Release IOAPIC pin when PCI device is disabled")

It seems like my machine doesn't like releasing the IOAPIC pin. Or,
maybe it is IOMMU-related and the IOMMU doesn't like this releasing of
the pin *after* the device gets suspended and *before* the IOMMU.

Strange.

Oh well, a well deserved lunch now :)
