Dear Christopher,

Thanks for your suggestion. I've done a few more experiments before and after updating the BIOS (to the latest version (4105 07/01/2013). Here are the results.

1. Old Bios. Mageia 3 + Fglrx driver
=> Worked fine

2. Old Bios, Kubuntu Trusty (installed yesterday, fully updated), Open-source (Radeon) driver.
=> No CPU hang.
However, I did have a problem with video-modelines being auto-detected wrongly, (resulting in the monitors showing out-of range. I've since fixed that manually with xrandr --addmode and will shortly file a bug on it, but this is what set me off on the path of trying the binary drivers).

3. Old Bios, Trusty, and the fglrx driver
(both fglrx and fglrx-update, as per https://help.ubuntu.com/community/BinaryDriverHowto/AMD )
=> CPIU hang.

4. Old Bios, Utopic alpha, and open-source driver
=> No cpu hang (but the modeline problem still present)

5. New Bios, Utopic, open-source driver
=> No cpu hang (but the modeline problem still present)

6. New Bios, Utopic, fglrx
CPU hang again (see dmesg attached)

Best wishes

Richard
