That patch http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff_plain;h=fe655d3a06488c8a188461bca493e9f23fc8c448;hp=b0b623c3b22d57d6941b200321779d56c4e79e6b seems to fix the problem:
# cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 0: 5580 4005 4004 3100 IO-APIC-edge timer 4: 488 93 3 231 IO-APIC-edge serial 8: 1 0 0 0 IO-APIC-edge rtc 9: 0 0 0 0 IO-APIC-level acpi 169: 2698 0 11062 16885 IO-APIC-level qla2300 177: 63677 0 0 0 IO-APIC-level eth0 185: 6 0 17417 0 IO-APIC-level eth1 NMI: 16778 16762 16758 16760 LOC: 16515 16561 16680 16704 ERR: 0 MIS: 0
Please put in in stable 2.6.14.x since it's quite important bugfix.
