Try it this way pls..... Directly after your BIOS has loaded you'll get a list with all your devices & their path on the PCI bus and also on the right the irqs which are used by the devices, what does this tell you? To stop the loading process simply press pause :-) Are there any devices which share/have the same number? > I was thinking that it was only disks on my ide0 and ide1 controllers > (ports?)

The thing is, at least with older machines that the bus speed is not high enough, so getting lots of network pakets and using an additional ide pci card (even worse on a shared slot) could cause such an effect. Intense work on 4 harddiscs and 1 or 2 network cards, could result in high cpu usage and, how to say that? high bus activity.....! Which also means that Requests from other "lower" devices on the systembus are "dropped".... at least held back. It's not so easy to explain it in English, I hope you get what I mean :/ > I am getting occasional "kernel: PPP: VJ decompression error" in my > logs.
