[openib-general] [PATCH] OFED 1.1-rc3 is ready

[Michael S. Tsirkin]

Well, it looks like the libipathverbs that went into 1.1 branch was botched.
How come?
Please note that Mellanox for one is unable to test libipathverbs at all.
libipathverbs maintainers, please, try to fix by Sunday.
And please, test the changes before you commit them.

Hi Woody,

So, we built everything using RC5 plus the libipathverbs from subversion
and we were successfully able to run ib_rdma_bw (with your arguments
above) and Intel MPI (a simple MPI hello world program).  I'm going to
continue testing with the Intel MPI testsuite and some applications ISV
applications.

I'll keep you informed.

Regards,
 Robert.
