Interestingly, I am seeing the same problem on two boxes with
2.6.2{5,6}. I haven't checked yet more recent kernels.

The odd thing was that booting with "nohz=off highres=off" did not
help, the only cure was to recompile the kernel and disable
CONFIG_HIGH_RES_TIMERS and CONFIG_NO_HZ.

This is the thread back then:
