nvidia interrupt problem

Hi,



In my search for the reason why the app_server doesn't work under haiku on my system (No, I haven't posted to the wrong mailing list), I stumbled into this:



"unhandled io interrupt 7".



The machine I'm testing haiku on mounts an nvidia geforce 2, so it uses Rudolf's driver.

To reproduce the problem (for people who have an nvidia card, of course)

Start haiku in "consoled" mode, and launch the test_harness app which comes with the r5 sample code (/boot/optional/sample-code/drivers/graphics/test_harness) and try to set any display mode. Bum! unhandled io interrupt 7. BTW it looks that the card is not tied to such interrupt line (at least, that's what the initial pci scan says, since listdev doesn't work yet on haiku... is there any other way to see which interrupt line it uses ?). The driver obviously works fine in beos, so this could be a kernel bug ?.



Is there anyone else who experienced this ?



P.S: I'm sending this to Rudolf too, just in case he's not subscribed to this list
