Comment 70 for bug 1041883

Ok. Tried this afternoon, after leaving off all day and without AC power. Booted without AC power and agin have the kernel panic issue and consistently - even from recovery. It's got to be something related to Ivy Bridge and the Intel HD 4000 I think. It gets to recovery, which isn't switching to the graphics and DRM stuff. I see the screen flash as it tries to go to graphics from text mode and then the panic occurs. I also noticed that when it finally does boot to the login screen that it flashes some errors. I checked the logs.

The error comes up:
[drm:intel_dp_i2c_aux_ch] *ERROR* too many retries, giving up

And then through to the loging screen/

Ok. One other thing I noticed, I actually had a lock up after continuing from recovery. The boot progress was going through on screen after I left the recovery screen, and then what appears to be a panic occurred but the text became corrupted, instead of switching to graphics output.

I don't know if this is helping any.
