Subject2.6.1 and irq balancing
Greetings all,

I upgraded my server to 2.6.1, and I'm finding I'm saddled with only
interrupting on CPU0 again. 2.6.0 does this as well. This is the
Supermicro X5DPL-iGM-O (E7501 chipset), 2 Xeons@2.4ghz HT enabled.
/proc/cpuinfo is normal as per HT, displaying 4 cpus.
2.4.2(3|4) exhibited this behaviour as well, until I applied patches
from here:
http://www.hardrock.org/kernel/2.4.23/irqbalance-2.4.23-jb.patch, et al.
