Hi,

I compiled the Torvalds git kernel 2.6.29-rc2-00013 and I got an oops.
The oops happens when ever X starts. Initially I was booting with run
level 5 and it hung. I tried to use run level to 3 and an operating
system started just fine. When I type startx the hung happen again.
Please let me know if you need some more information besides oops from
messages file and lspci output.
