Um what kernel version? Is this the latest umr? Maybe capture a trace of umr to see what is happening.
It works just fine on my raven1.

What options should I specify in kernel command line?
On my setup `umr` terminated with message `Could not open ring debugfs

$ sudo umr -O verbose,halt_waves -wa
Cannot seek to MMIO address: Bad file descriptor
