Guessing wildly but educatedly, I'd say someone is counting timer ticks in a 32-Bit unsigned. The alpha's timer interrupts at 1024Hz AFAIK which would result in said 48 days.
Rahul> Has this been seen before, and is it fixed in the newer kernels?
Haven't looked into it (see above), but I hope it will be fixed, otherwise the i386 machines will have the same problem, even if only after over a year. (Yes, linux is provably stable enough to keep up that long !)
