Mmhm, as I was (kindly) cc'd I reply my results so far, but since there was a mention of IRQBALANCE, I checked myself, since I was pretty sure I have switched that off: # zegrep IRQ /proc/config.gz CONFIG_GENERIC_HARDIRQS=y CONFIG_GENERIC_IRQ_PROBE=y CONFIG_GENERIC_PENDING_IRQ=y CONFIG_IRQBALANCE=y CONFIG_HT_IRQ=y CONFIG_IDEPCI_SHARE_IRQ=y CONFIG_HPET_RTC_IRQ=y CONFIG_TRACE_IRQFLAGS_SUPPORT=y # CONFIG_DEBUG_SHIRQ is not set Darn, I'd say. I go and switch balancer off, it doesn't really do much good for me anyway. (What about userland balancer, does it hose things as well?) But apart from that I'm runnig under " pci=nomsi " for the last 4 days without a freeze (which usually occured every 1-2 days, but I'll wait for more, and I will try to bonnie++ myself in the meantime). It did not freeze under "acpi_irq_balance" either for 6 days, but the machine overall felt a bit jerky (pretty ugly irq overlaps I guess). If any of you prefer me to run under other options, or to apply that patch I was advised to, I'll just do that. Just voice yourself. (I have an open request for "noapic acpi_irq_nobalance" and the patch.) Thanks for your time, as always (and I try to share mine :)). -- byte-byte, grin
