Could that be the fault of a buggy BIOS or chipset? For what it's worth, I saw this problem on both a FIC PA2013 motherboard (I forget the pci chipset used there) and an ABIT KT7A with a VIA Apollo KT133 chipset. > > I can't tell if it is a bug in the National Semiconductor chip on the > > card or with the driver.

I did move it to a different slot at one pointin an attempt to make sure it was sharing interrupts with different devices, but maybe it still got stuck sharing with a buggy driver. > > Between this bug and the natsemi driver's broken multicast support, > > It was broken on my initial version, but I fixed it.

I had no trouble duplicating the problem in the original driver (assuming, of course, that the version of natsemi.c included in Linux 2.4 counts as "original"). I didn't start hacking on the driver until I experienced this problem. As I said, I experienced it with two different motherboards, and now there's another person here on debian-user experiencing the same problem. In my case, most of the PCI cards were common between the two motherboards, so I'm not ruling out the idea that the natsemi card was sharing an IRQ with a misbehaved driver. There was a SCSI card in the configuration (using the sym53c8xx driver), so that may have been involved. But as I said, I don't know right now which cards were sharing IRQs. noah -- _______________________________________________________ | Web: http://web.morgul.net/~frodo/ | PGP Public Key: http://web.morgul.net/~frodo/mail.html
