Description Jeff Layton 2010-07-01 12:01:18 UTC

Created attachment 428365 [details]
serial console log of boot attempt

Installed RHEL6 on one of my older workstations. It has an integrated intel video chip. When I boot this machine without "nomodeset" it seems to panic. The screen never shows anything after it tries to switch the mode, and the caps lock and scroll lock lights blink. When I boot with nomodeset, it comes all the way up, but X won't start (unsurprisingly).

I hooked up a serial console to the box, but it never shows an actual oops. Full copy/paste of the screen console is attached. The machine is running kernel 2.6.32-37.el6.i686, but I got similar results with an earlier -33.el6 kernel.

A work-around

A workaround that let me boot; drm_fb_helper_set_par() is probably really not a good place for a fix though.

Comment 5 Lubomir Rintel 2010-07-06 20:41:23 UTC

The following upstream commit fixes the issue:

commit 6349d7ca97b035c4363365b890ec1f39d41b7b51

    drm/i915: fix oops on single crtc devices.
    
    (regression fix since fbdev/kms rework).
    
    My fb rework didn't remember about the 84/65s.

patch -- fix oops on single crtc devices

Thanks Lubomir, this patch fixed the problem for me too. With this, the machine boots and X starts.
