I seen that on one computer too, with 2.5.59. For some strange reason IRQ0 from timer was stopped, and thus system reported jiffies + tsc / <host_cpu_freq> as current time, taking only 32bit tsc into account. After I disabled irqbalance, problem never reappered (it was two cpus PIII from Dell, with serverworks chipset & 8GB memory; I do not remember model number).
System worked in that state for several minutes, until it lost some NFS reply, which it never retried due to stopped timer... Best regards, Petr Vandrovec vandrove@vc.cvut.cz
