Tesla C2050 does not work

[russoribas]

When I boot my system with our brand new Tesla C2050 and run nvidia-smi I get:

8<-------------------
root@alt:~# nvidia-smi -a
NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).
Failed to attach gpu
Could not allocate resources!
root@alt:~#

from dmesg:
[ 441.201206] NVRM: RmInitAdapter failed! (0x27:0xffffffff:1047)
[ 441.201229] NVRM: rm_init_adapter(0) failed

When the same machine is booted with our old Tesla C1060 everything goes well

This is not udev problem, we have 3 teslas C2050 and all of them have the same problem on
different machines (but same configuration such as motherboard,proc,ram). I already tried
different slots but did not work. Booting on a intel base machine the board worked like a charm. Also the light is green on the Tesla.

It is attached my nvidia-bug-report.log.gz to check what is happening.

Thanks in advance

If someone can say something please tell me, I'm with this problem

Perhaps try using MSI for interrupts.
(and shouldn't you have proper support from nvidia if you have tesla hardware?)
