I am under the impression that it only makes sense to call the ATIF method if the graphics device has an ACPI handle attached. So we could skip the call altogether if there is no such handle.

Use the proper macro to issue the debugging message in radeon_atif_call(). Otherwise we spam the log of many systems with a message which looks like an error message of unknown origin, and could thus confuse the user. Commit dc77de12 was a first step in this direction, but was not sufficient IMHO.

There are GFP_ATOMIC allocates in the provider routines, so this is possible and should be dealt with. The test that induced the failure is associated with a host SM on the same server during a shutdown. This patch causes ipoib_mcast_join_finish() to exit with an error which will flush the queued mcast packets. Nothing is done to unwind the QP attached state so that subsequent sends from above will retry the join.
