Peter de Schrijver has tracked this down to a bug in the interrupt handler. The handler currently does not check whether an interrupt is masked and calls the handling routine for _every_ interrupt, not only for those that are not masked out currently. The following patch fixes this. Ralf, could you please apply the fix to the CVS? Good find, applied to CVS. The patch works great here! Liam |
