I’m running two GTX680s in an Ubuntu 12.04LTS box. After a reboot, I noticed I could use one card immediately but not the other. nvidia-smi gave the error “could not open device file /dev/nvidia1”
I took a look at /dev/nvidia0 and /dev/nvidia1 … their timestamps are six minutes apart.
crw-rw-rw- 1 root root 195, 0 Apr 18 14:03 /dev/nvidia0
crw-rw-rw- 1 root root 195, 1 Apr 18 14:09 /dev/nvidia1
crw-rw-rw- 1 root root 195, 255 Apr 18 14:03 /dev/nvidiactl
Syslog didn’t catch anything of interest. All of the nvidia entries match the timestamp of /dev/nvidia0. No explanation of the delay there.

Should this delay worry me? Or is it just normal settling time?
Thanks in advance.
