Hi Peter,
This is expected if the following configuration is not in place, please see below:
In the RN, and confirmed by engineering, only following OS supported (without extensions) (ie: 14.04.02,.03,.04):
• RHEL 7.0/7.1/7.2
• SLES12/12.1
• Ubuntu14.04, Ubuntu15.04
The right combination is to choose OS from the list with distro kernel and install mlnx_ofed.
You can also use upstream kernel (the target core is more stable there) instead of mlnx_ofed in order to run isert.
So to clarify:
1) Either Ubuntu 14.04 or 15.04 (no extension) + Mellanox OFED driver.
or
2) Ubuntu 14.04 or 15.04, upstream Kernel with INBOX driver.
Thank you,
Sophie.
