I'm referring to these:
ib0: multicast join failed for ff12:401b:ffff:0000:0000:0000:ffff:ffff, status
-11
The patch in http://lists.openfabrics.org/pipermail/general/2008-May/050551.html
is causing them.
The patch creates a state when there is no sm_ah, so all alloc_mad() calls
return -11 (-EAGAIN), this goes back to ipoib multicast join: ipoib asks the sa
to join, it queues work that calls send_join(), this calls
ib_sa_mcmember_rec_query(),
this one calls alloc_mad() and gets -EAGAIN.
How about lowering the severity of this error in ipoib_mcast_join_complete()
from warning
to debug?
