Hi Dmitry,
I can almost guarantee that this is caused by inadequate cooling of your
M2090 card. The fact it locks the machine up is key. I have seen exactly the
same issue with test cards I have in homemade machines. The M2090s have to
be in a properly ducked chassis designed specifically for them. I would
suggest both sending the card back under warranty and contacting the
manufacturer of your machine to find out if their cooling system is properly
certified for M2090 cards. If it is then you might want to check for
malfunctioning fans etc but most of these 1U or 2U server chassis for
M2090's have full fan monitoring and alarms so if there is a fan issue it
should already be alarming.
Out of interest what is the exact specs of your system? Who makes it? If you
let me know the model and the manufacturer I can try to escalate within
NVIDIA.
All the best
Ross
