OK, didn't get time to try 3.7-rc1. So, instead, installed 3.7-rc5 based Ubuntu
kernel from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc5-raring/

(specifically, following files:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc5-raring/linux-headers-3.7.0-030700rc5-generic_3.7.0-030700rc5.201211110835_amd64.deb

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc5-raring/linux-headers-3.7.0-030700rc5_3.7.0-030700rc5.201211110835_all.deb

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc5-raring/linux-image-3.7.0-030700rc5-generic_3.7.0-030700rc5.201211110835_amd64.deb

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc5-raring/linux-image-extra-3.7.0-030700rc5-generic_3.7.0-030700rc5.201211110835_amd64.deb
)

With this, situation is no better. In fact, with this kernel, I cannot even
switch to a tty to restart X - which works happily on my current
3.2.0-32-generic
(package: "linux-image-3.2.0-32-generic" version: "3.2.0-32.51").

There is no significant message logged in the syslog with 3.7-rc5 which can
point to a problem. Attaching the dmesg output and Xorg log anyways.

Thanks,
Kunal
