The timer_interrupt() routine did not scale lost real ticks to logical ticks correctly. This could have caused time drift for 64-bit Red Hat Enterprise Linux 5: KVM (Kernel-based Virtual Machine) guests that were booted with the "divider=x" kernel parameter set to a value greater than 1. "warning: many lost ticks" messages may have been logged on the affected guest systems.
