Now you would also need to tell us what IRQ 50 relates to (i.e. where in the group of presumably multiple MSI-X vectors that device uses this sits). Plus, for an edge type interrupt to be raised repeatedly and wrongly, the device doing the respective bus master writes must be doing something odd (perhaps because having been programmed wrongly). For understanding what's going on here, providing 'i' and 'M' debug key output might be pretty helpful. And finally - 2.6.32 is pretty old. Do you also see the problem with a more modern kernel (trying to exclude possible driver issues)?
