Previously we printed, e.g., do_IRQ: 0.242 No irq handler for vector (irq -1) There's no clue about what "0.242" means, and the IRQ number, which is the important generic information used by drivers and /proc/interrupts, is almost an afterthought. Change the format to this: No handler for IRQ -1 (CPU 0 vector 0xf2) Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> --- arch/x86/kernel/irq.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-)
