      Description

      This update fixes the following bug:

      • An insufficiently designed calculation in the CPU accelerator in the previous
        kernel caused an arithmetic overflow in the sched_clock() function when system
        uptime exceeded 208.5 days. This overflow led to a kernel panic on the systems
        using the Time Stamp Counter (TSC) or Virtual Machine Interface (VMI) clock
        source. This update corrects the aforementioned calculation so that this
        arithmetic overflow and kernel panic can no longer occur under these
        circumstances. (BZ#781974)
