Hello!
after upgrade from 1.9.0 to 1.9.2 I see errors:
/usr/sbin/irqbalance[1466]: Cannot change IRQ 93 affinity: Input/output error
/usr/sbin/irqbalance[1466]: IRQ 93 affinity is now unmanaged
switching back to 1.9.0 solves problem
Any ideas?
btw, looks like problem exists only on servers with amd processors.
