I have built a kernel from the upstream mainlinekernel following this
doc: https://wiki.ubuntu.com/KernelTeam/GitKernelBuild
The kernel was version 3.9-rc4.
Booting in to this v3.9 kernel has solved my problem.
Looks like there were a lot of commits in the drivers/gpu/drm/radeon
area going
these commits happened between rc3..rc4:
9305ede6afe2998 radeon/kms: fix dma relocation checking
51861d4eebc2ddc radeon/kms: force rn50 chip to always report connected on
analog output
25d8999780f8c1f drm/radeon: fix error path in kpage allocation
a6b7e1a02b77ab8 drm/radeon: fix a bogus kfree
And also information from avivotool taken once the error occurred.
Please let me know if you need any more information.
Thanks.

As per instructions on providing information about GPU lockups on the
Wiki this is the dmesg output with the error.
