I don't know if this is just G2 flakiness, but if I start playing sound and then start hotplugging devices then I will sometimes get this sort of oops (these don't down the system but they can make it unstable) - any clues as to what might be the issue (these are now quite old -rc2? kernels...)... just wondering if anybody can see anything obvious?
