Since this problem is timing based, using tracing is not going to
help. You could try turning on instrumentation and when the crash
occurs take a look at the instrumentation buffer from JTAG and see
what was happening just before.

Given that eCos doesn't exhibit this problem on other platforms, the
most likely cause of this is a bug in the LPC2xxx HAL. So you should
probably concentrate your efforts there.
