This is a bit of a rare problem, I have not been able to debug or fix it or find anyone else with the issue. I hope someone here can help me out.

Once in a while, I boot up Windows XP from the first partition of the first disk (using grub, the computer dual-boots ubuntu) and it hangs as the Windows XP splash image fades in, leaving the screen with a dim image of the splash screen. After 2-3 minutes, it continues to boot as normal, no error messages or strange behavior.

I have noticed that this happens about 75% of the time when the last time the computer was shut down it was from Ubuntu, and maybe 5-10% of the time otherwise.

I have looked at system logs as far as I was able, and did not find anything the miss. What is causing this and how can I fix it?
