I personally think most of these issues are red herrings. Most interrupts should not be held long enough to interfere with the tdm interrupts, possibly with the exception of video interrupts routines. There should not even be a problem with shared interrupts. One thing that could make a lot of difference is the pci bus latency settings. Since this depends on all the other elements on the pci bus as well this may cause things to miss their deadlines. Since the TE405 (unlike the older T1/E1 adapters) is bus mastering this can be an issue. Of course, if there is sufficient buffering on chip this point is moot. Some bioses get the caluclations wrong, or at least used to. This made some cards miss their deadlines. Does anyone know if this could be the source of some of the problems people are experiencing? As a reference we have missed the deadline on 824 out of 3034245416 interrupts on our machine (2 E1 circuits, Fujitsu 1U server, one ide disk) even though we have hit the disks pretty hard from time to time.
