Hi,
i've just upgraded FBSD6.2 to 6.4 by freebsd-update.
Everything works perfect except this:
interrupt storm detected on "irq14:"; throttling interrupt source

Code:
vmstat -i:
interrupt                          total       rate
irq0: clk                         644186        998
irq1: atkbd0                           7          0
irq7: ppc0                             1          0
irq8: rtc                          82446        127
irq9: atapci0+                      9247         14
irq10: xl0                          3601          5
irq14: ata0                       646892       1002
irq15: ata1                         3285          5
Total                            1389665       2154
I raised hw.intr_storm_threshold from default 1000 to 20000 but
it didnt help.
I found something strange in dmesg:
pci_link3: BIOS IRQ 14 for 0.31.INTD is invalid
but i dont know how to deal with it.

Any ideas?

TIA

[Solved]

Ok, problem solved.
For future generations:
Fbsd 6.4 seems to have problem with irq handling.
I turned off irq14 on computer's bios (made it reserved) and problem disapeared.
Thank you for your attention ;)
