[ofa-general] RE: CM Enable SRQ for less than 16 s/g - bug

I meant that the test hangs but not the system. You can still ping hosts on the ipoib interface, it is just that the test never ends. You can press Ctrl C and restart the test again.

Sure, can you provide some more details about this hang like a stack trace?
Bulk of the changes this patch introduces are in ipoib_cm_dev_init(). So, it should not affect the send and receive paths. Not sure why the hang occurs.
