Hey rohith, i have an ASUS P7H55M-Pro moboard and was having trouble with my existing DSDT as well. Worked fine under SL, but failed at IOAPIC under Lion. I followed samisnake's Guide to create your own DSDT (the link's in his signature in this thread) and it worked like a champ.

Haven't figured out why yet, but happy that the system is up and running again.

Good luck.

NO samisnake i did a clean install with unibeast and user DSDT install with multibeast
