Bug Description
Trying to run the installer (doesnt matter if d-i or ubiquity) the kernel spits out an unhandled fault error when trying to detect disk drives:
Apr 12 11:18:47 main-menu[208]: INFO: Menu item 'partman-base' selected
Apr 12 11:18:48 kernel: [ 556.388214] Unhandled fault: external abort on non-linefetch (0x1018) at 0x40200000
Apr 12 11:18:48 main-menu[208]: (process:7234): Bus error
after an IRC conversation it was suggested it might be caused by turned off clocks:
<ogra> amitk, cjwatson suggests its misaligned memory access
<amitk> ogra: I am almost sure it has to do with clocks being turned off during module access

This definitely seems like an issue with clocks of the HW module being off when it is accessed.
Please provide the exact set of commands that triggers this within d-i. I don't even know where to begin with d-i.
