Have a look into /proc/interrupts to see which drivers are registered for irq 18 (e100 in your case), then search in the output of "lspci -v" for any _other_ devices that use irq 18. It's also possible that one of the drivers is buggy and mistakenly said "this interrupt is not from my device", or, in theory, that the BIOS is buggy and has mislabeled some device's interrupt. According to Google, there are other reports of this message with the e100 driver. Does your network work? If not, does irqpoll help? Regards, Clemens
