If it still occurs, please reopen. ---------------------------------------- Bug #1182: intr 11 livelock with SMP http://bugs.dragonflybsd.org/issues/1182 Author: Michael Neumann Status: Closed Priority: Normal Assignee: Category: Target version: Hi, UP works perfectly, SMP has this intr 11 livelock problem, which slows it pretty down, so that network does not work. I post output of dmesg for both UP and SMP as well as the output of vmstat -vi. Maybe those information are helpful to someone :). I also tried SMP with a recent kernel (the outputs below are of a kernel which is a few month old), but it's even worse; it stops at "intr 7 livelocked limit engaged" during ATA probing. Looking at "vmstat -vi" it's obvious that the problem is with atapci1. Also notably is the huge difference of "irq0: clk", which is ~1600 for UP and ~13000 for SMP. I don't know exactly what rate means here, but if it means interrupts/second and it's the clock interrupt which usually fires at 1000 Hz, then something is seriously wrong.
