Bug Description
... so sound doesn't work unless the snd-aaci module is loaded by hand.
This appears to be a regression at some commit in linux-linaro-
At least the head of linux-linaro-natty appears unaffected.
Observed in linux-image-
For now, it looks like loading of AMBA peripheral drivers may not work usefully.
This needs investigation and (probably) a proper fix, which may involve additional udev rules, a change to the uevent data associated with these devices etc.
In the short term, this can be resolved by building the relevant AMBA drivers into the kernel for vexpress.
All of them seem to be built in already except for the AACI driver.
CONFIG_
This also appears to require the following also to be built in:
If boards other than vexpress are making use of the ARM AACI driver, they may be affected too.

Set medium priority as a work around is known: snd-aaci module is loaded by hand.
Assign to john to update the kernel config.
