Sounds like bad memory timings to me. We got the same symptoms when we
overclocked an SA1100 without adjusting the DRAM timings. On the SA1100
the DRAM timings are closely related to the core clock speed. If the
SA1110 uses the same mechanism, you should just recalculate and set the
DRAM timings for the higher clock speed.
