[openib-general] "ib0 already has pending op 2" ???

[Ira Weiny]

I have put svn 6829 on our test cluster here and I am getting this error again.
(I used to get it a while ago but it went away.  I figured something had been
fixed as time went on.)  This stack was backported to 2.6.9 using Woody's
patch.

May  4 14:37:27 odev1 ib_at: ib_dev_ats_op: dev (ffffffffa00dbcc0) ib0 already has pending op 2

What does this mean and how can I get rid of it?  ibv_rc_pingpong is not
working and ib0 is up but not working either.  I saw this some time ago and a
reboot would clear it up.  Is this something stuck in the hardware?  I tried a
power off and that did not clear it up either.
