Just a recommendation, since you've obviously never done the whole upgrade before, I recommend using a GENERIC kernel to start with unless there are serious problems with that (you're system crashes on probe of some device, etc.) The reason for this is that there are a number of simple little gotchas in kernel configuration the get even experienced people if they aren't paying quite enough attention and so it's much easier to just use GENERIC at first. Later you can move on to a custom kernel. > They are with devices I never use, but perhaps they generate interrupts > sometimes anyway.=20 >=20 > IRQ 3: Used by sio1 and the ep0 PCMCIA card.

Both of those are more or less ISA devices and ISA can't share interupts (with minor, irrelavent exceptions). > IRQ 5: Used by the USB controller and the sound card. This is likely harmless since pretty much all USB and sound devices are PCI these days. > I don't ever use USB devices, and I don't even have usb support built > into the kernel. Is this a potential problem anyway, or is it harmless? Not having the device in the kernel is probably harmless. Personaly once everything else works, I'd take a shot at getting USB working just for kicks. You can test it with a cheap ass mouse or something. > As for IRQ 3, I've now set up pccard.conf to use IRQ 9 (which is unused) > and we'll see what that does for the state of my system.

Enabling bridging does poke the ethernet hardware slightly (when enabling promiscuous mode) so that could actually be the problem. There definatly have been problems with bridging that have been fixed between now and the 4.2 release so there's a good chance that an upgrade will make them go away. As I think I mentioned before, bridging just isn't used by most people. VMWare is making is much more popular and it should become much more solid then before. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
