Re: kern/49398 (i386-current GENERIC (i915drmkms) boot hangs if monitor powered off)

Via the serial console, can you get a stack trace from ddb?
If not, we can try printf debugging. I'd start by adding printfs
around all the calls to drm_add_edid_modes in i915, and throughout
drmfb_attach. That should be enough to get started, but I can supply
a patch if you'd like.
Also: does this happen on any machine other than your i845?
