kernel: do_IRQ: X.Y No irq handler for vector (irq -1)

Одно из объяснений данной ошибки:

The Intel 5520 and 5500 chipsets do not properly handle remapping of MSI and MSI-X interrupts. If the interrupt remapping feature is enabled on the system with such a chipset, various problems and service disruption could occur (for example, a NIC could stop receiving frames), and the «kernel: do_IRQ: 7.71 No irq handler for vector (irq -1)» error message appears in the system logs. As a workaround to this problem, it has been recommended to disable the interrupt remapping feature in the BIOS on such systems, and many vendors have updated their BIOS to disable interrupt remapping by default. However, the problem is still being reported by users without proper BIOS level with this feature properly turned off. Therefore, this update modifies the kernel to check if the interrupt remapping feature is enabled on these systems and to provide users with a warning message advising them to turn off the feature and update the BIOS.

TROUBLESHOOTING: Some systems have trouble supporting MSI and/or MSI-X
interrupts. If you believe your system needs to disable this style of
interrupt, the driver can be built and installed with the command:
# make CFLAGS_EXTRA=-DDISABLE_PCI_MSI install
