Windows XP takes a long time to load, mup.sys problem?

[mr saturn]

My system boots fine until the Windows XP loading screen, where the bar goes for about 30 'loops'. It finally seems to load correctly and the leds on my G15 light up and the welcome splash screen displays shortly after.

I tried formatting my OS partition (the boot sector is on a different drive, could that be the problem?) and reinstalling windows, and the problem persists. I enabeld boot logging and here is the file I got.

I think you get the idea. Random other drivers would load, but it seems things take a dive after mup.sys. The system still boots (amazingly, after that log I would have expected more problems), it just takes a looong time.

Anyone have any ideas?
