[openib-general] cmpost: failure sending REQ: -22

[Jeff Carr]

Has anyone seen ib_send_cm_req() return -22?

I seem to be stuck with this error today. I've seen it in the past; and 
it seems to have gone away without my being able to discern a conclusive 
reason. Usually rebooting the systems will cause it to work again.

This go around, It's really refusing this time; I reverted to kernel 
2.6.11.7 and infiniband sources from around the end of april (even 
binaries I built then that were working don't work now.)

I rebooted the SM also, but now I'm going to actually powerdown the 
systems. Although it seems like it shouldn't be possible, this behavior 
really makes it look like the HCA can get in a broken state that 
persists after a reboot.

Enjoy,
Jeff
