march Jun 27, 2017 3:35 AM (in response to ramakris)Hi,
Can you please tell me which kernel version do you use ?
I need to check what is the status of this patch in the MOFED driver.
Can you send me your lscpi output of the Mellanox Adapter you use and his PSID, and the driver version.
>lspci -xxxvvv | grep -i mellanox
>mst start
>mst status -v
>flint -d /dev/mst/<device see above> q (query to get PSID)
>ofed_info -s
Thanks
Marc

I am not using MLNX OFED stack. I am using inbox driver. that is our main requirement. But with MLNXOFED also we are getting random write failure. The crash I have to you is not MLNX OFED one. it is inbox driver.
