19 dec == 13 hex :-)
/proc/pci reports IRQ numbers in hexadecimal (nobody knows why, but we're
probably forced to keep this for compatibility), the rest of the kernel uses
decimal numbers. On the other hand, the whole PCI subsystem uses hexadecimal
numbering of PCI slots with exception of /proc/pci using decimal ones...
Have a nice fortnight
