Hey FZ,

I ran into an issue that I can't figure out how to fix.  I've got 12 gpus on a TB250-BTC Pro, and all of them work fine, except the last one GPU12 (PCI:12:0:0) which doesn't seem to start an xserver instance on boot.  Because it doesn't load xserver, the fan and power settings are unavailable for editing, so the card runs too hot and causes power throttling, and occasionally a reboot.

Any idea how to fix that?  I checked the /etc/X11/xorg.conf file and it looks fine from what I can tell (all display device settings are there and look the same).

Thanks for your help.
