Hmm, 10-15 mins .... has it got fan, is it getting too hot ? (wind
blowing the wrong way ;)

Hmm, could be the copro is sensitive to the heat. Does hlt effect the
copro, or just the cpu, ie the cpu is keeping cool enough because it's
lightly loaded, and being hlt'ed (a low power consumption mode), but the
copro is running just as hot as ever. Well it's just an idea ....
