Miles, could you try the patch below? (Andrew: if this solves Miles' problem then i think this is v2.6.18 material too. [The other possibility would be some permanent stack-trace entries leak, in which case the patch will not help. If that happens then we'll have to debug this some more.])

----------------> From: Ingo Molnar <mingo@elte.hu> Subject: lockdep: double the number of stack-trace entries
Miles Lane reported the "BUG: MAX_STACK_TRACE_ENTRIES too low!" message, which means that during normal use his system produced enough lockdep events so that the 128-thousand entries stack-trace array got exhausted. Double the size of the array.
