Comment 3 Chuck Ebbert 2008-01-29 21:17:52 UTC
The faulting instruction in memory:

  0:   2b 44 28 1b             sub    0x1b(%eax,%ebp,1),%eax

The instruction in the shipped kernel:

       2b 46 28                sub    0x28(%esi),%eax

A single bit has flipped in memory. This means the system almost certainly has
bad memory or some other kind of hardware problem.  The other reported bug is
similar, so I will close both of them as NOTABUG.
