[OpenIndiana-discuss] resolved - sort of, now a reproduce-able bug was Re: A KVM switch broke my server?! Lightdm is panic'ing the kernel

[Carl Brewer]

Ok, the trigger for the fault, reproduce able, is to boot the box 
without anything plugged into the HDMI port on the GFX card. That seems 
to break something in the BIOS, then the only way to get it to start X11 
without a kernel panic is to restore the BIOS from a previous saved version.

Tried without KBD & mouse, and HDMI monitor plugged in, and despite the 
O/S not being smart enough to notice and then use the kbd or mouse after 
re-connecting, which while annoying, isn't a show stopper. But if 
nothing's plugged into the HDMI port, it does something weird to the 
BIOS and we're busted. The only way to get X11 working again is to 
revert the BIOS.

It will run ok if you disable X11 (disable lightdm), but if you try to 
start X11, you get a kernel panic. The only way I've found to 'fix' it 
is to revert the BIOS.

Is there something in the NVidia driver that could muck with the BIOS?

This is odd.  Very odd.
