Hi everyone, newbie here... I'm in the process of migrating to DragonFly for my main desktop as I figured it would make more efficient use of SMP than my former OS of choice. Ironically the problem I'm running into is core 0 seems to be constantly maxing out with about 60-70% going to Interrupts and the rest to System. This happens both under heavy loads:

My FS is HAMMER on a dm-crypt device and this is an EFI install on a single hard drive. I'm not sure what it is that I'm doing wrong here but any pointers would be much appreciated... Mike
