Subject: do_IRQ: 0.126 No irq handler for vector (irq -1)

Hello list,

i've 36 servers all running vanilla 3.18.18 kernel which have a very
high disk and network load.

Since a few days i encounter regular the following error messages and
pretty often completely hanging disk i/o:
[535040.439859] do_IRQ: 0.126 No irq handler for vector (irq -1)
[548400.353679] do_IRQ: 2.109 No irq handler for vector (irq -1)
[551624.894507] do_IRQ: 4.84 No irq handler for vector (irq -1)
[557524.288691] do_IRQ: 1.158 No irq handler for vector (irq -1)
[559786.928441] do_IRQ: 3.172 No irq handler for vector (irq -1)
[572906.281394] do_IRQ: 3.72 No irq handler for vector (irq -1)
[576611.808128] do_IRQ: 3.118 No irq handler for vector (irq -1)
[577242.682643] do_IRQ: 2.45 No irq handler for vector (irq -1)
[578524.584545] do_IRQ: 5.190 No irq handler for vector (irq -1)
[602109.548268] do_IRQ: 3.101 No irq handler for vector (irq -1)

All systems are Single E5 Xeons and I'm running irqbalance on them.

Chipset:
Intel C602J chipset

Is there anything i can do to fix this? Is there may be a kernel patch
available?

Thanks!

Greets,
Stefan
