I can fix irqbalance no problem, however I like the kernel approach as well, since it's not just irqbalance that moves irqs, sysadmins tend to do it as well.... so how about both? One thing we probably should do, and that would help irqbalance immensely, is to export a bitmask for which cpus an interrupt CAN go to, next to where the current binding interface is. I'll check into that Hidetoshi: would it be possible to send me a /proc/interrupts file of that machine? -- if you want to mail me at work (you don't), use arjan (at) linux.intel.com Test the interaction between Linux and your BIOS via http://www.linuxfirmwarekit.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
