nVidia Xorg driver 340.76 causes lots of troubles in UEFI boot:
1. Does not load from /boot/loader.conf, only kld_load in /etc/rc.conf.
2. Hangs computer after some time of inactivity in Xorg (after xscreensaver is launched). Probably APM related. Only hardware power-off is possible. No problem when machine works for a long time in console mode with no Xorg running.

New nvidia driver does not work on my GF GT9800GT which I don't really want to replace as it has no-fan cooling.

No kernel coredump is possible.

Please fix nVidia driver in UEFI boot/kernel :-)
Comment 1 Tomasz "CeDeROM" CEDRO 2015-07-24 11:09:26 UTC
I have traced the issue to be caused by "ErP READY" BIOS settings.

When ErP is enabled nvidia crashes, probably because system shuts down the power to the video card. When ErP READY is disbaled in BIOS no crash occurs.
Comment 2 Tomasz "CeDeROM" CEDRO 2015-07-24 12:38:26 UTC
Negative. Although ErP power management is disabled in BIOS system still crashes after some time of inactivity. This is critical and does not allow to use UEFI+XORG+NVIDIA.

GPU is ASUS GF9800GT, not supported by newer driver.
