Hello, I've upgraded kernel (Debian Squeeze - backports) from 4.6 (4.6.4-1~bpo8+1) to 4.7 (4.7.2-1~bpo8+1) and IRQs stopped working with error messages like this:
ACPI: No IRQ available for PCI Interrupt Link [LNKD]. Try pci=noacpi or acpi=off The same thing appeared on two different machines. Is it a known/fixed bug? -- Ondrej Zary
