Sorry for the delay, I could not get physical access to the machine
for the last days.
I was able to do some more testing today and found this:
- The problem is not the IRQ /sharing/, after getting rid of all the
other PCI cards, the problem was still there.
- The only thing that seems to have any effect on the symptoms is the
presence of the USB driver, either usb-uhci or uhci. I am not using
USB at all. As described before, the system behaves is either of those
ways:
* epic100 driver without DMA mapping (e.g. 2.4.0-ac9): normal operation
* driver with DMA mapping+USB driver loaded: lots of interrupts -> slow
* driver with DMA mapping, USB driver not loaded: hang after ~2 seconds
- I sometimes get 'spurious interrupt: IRQ7', even though no device is
connected there. Probably not important.

Can't see right now, system was bought in October 2000
I think it was 1.004, but I am not sure.

Still no improvement until latest -ac (2.4.1-ac13)
