My pc has ubuntu 13.04 alongside window 8. Last time I used my pc (in ubuntu) is 5 days ago and it was fine. Today I tried to boot into ubuntu but failed. Normal boot seems to stuck forever at the purple ubuntu screen with nothing on it. I also tried to select recovery mode in grub screen. What happened is the screen(command line) was flooded by this line
udevd: timeout: killing '/sbin/modprobe -bv pci:v000010DEd00000DC4sv000010DEsd0000085ABc03sc00i00' 
I also tried to run boot-repair in live-USB. Nothings worked. This is the paste log from the boot-repair. >> http://paste.ubuntu.com/6133079/
Window 8 is still working. Any help is very appreciated. Also this is my first time posting on this I dunno what I need to tell.
