Ok, compiling ... will report soon. The reason I've asked - this
particular brand new box is freezing once at a 2-3 days without any
output - no oops, no sysrq, nothing. So I'm trying to investigate what
is the problem. The previous kernels (3.3.x) have the serious problem
with iommu - the onboard USB3.0 and Ethernet did not work at all on
them. The 3.4.x is better, but seems like still freezing.

Thanks
