Comment 48 for bug 66900

Had tried based on the May 9th feedback

a) irqpoll did not help
b) looked at updated 3.5 version bios - that sorted out the issue.
However, now during direct boot, I do not get the grub selection menu. (But it is manageable - by instinctively selecting the first or last option in my dual boot)

Interestingly, if I do a reboot (instead of shutdown), the grub options come up fine.
