Hi, having another "card freeze" issue with linux-next (tag next-20150128) on a server running 3 solo6110 cards. The freeze happens after 3 days or so. Much better than 30 minutes, which was the case before the recent enhancement by Krzysztof Halasa. This is Ubuntu Trusty. There's /usr/sbin/irqbalance process running. See interrupt stats here: https://gist.github.com/krieger-od/f8d99080d6fc30dad3d2 I wonder why all solo6x10 interrupts happen on CPU0, while there are 3 more cores.
However, I have got an idea reading this: Irqbalance is a daemon to help balance the cpu load generated by interrupts across all of a systems cpus. Irqbalance identifies the highest volume interrupt sources, and isolates them to a single unique cpu, so that load is spread as much as possible over an entire processor set, while minimizing cache hit rates for irq handlers. Disabled irqbalance launch on boot. Rebooted, and the host got down up to now :( Any comments, except laugh? :) -- Andrey Utkin _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
