Right after configuring my display (intg:off, ext:1920x1200) some kernel oopses occurred.

remove the vesa fb driver or vga= from your grub config.
Comment 4 Elmar Stellnberger 2011-01-10 09:30:53 UTC
 Vesa fb does not appear on the kernel command line; lsmod | grep -i fb or vesa does not return anything either (as booted with the radeonhd driver).
 Why should vga=0x375 disturb? I want to have it for a higher resolution in text mode. - and the initial graphics mode setup has worked well.

the drm fb driver will automatically take care of the higher res console. vga= is not compatible with the drm fb.
Comment 6 Elmar Stellnberger 2011-01-10 10:01:02 UTC
Yes; and how to make sure that vesa fb does not get loaded (and how to check for it)?
Comment 7 Elmar Stellnberger 2011-01-10 11:30:45 UTC
 Well; the oopses didn`t seem to go without vga=0x375, -> see hang #4.

 This time the hang was more complete than usual. The mouse did not move at all any more (no more reaction on input any more) instead of just moving in slow hulking steps.
Comment 12 Elmar Stellnberger 2011-01-10 11:46:34 UTC
  Please do also keep the vga=0xNNN option supported! I really don`t want to do without since I do or often have to work without X - and working with a 80x25 text console is really no pleasure. - If X is broken, please don`t also take me the text console!
Comment 13 Alex Deucher 2011-01-10 12:37:12 UTC
Your system looks pretty screwed up.  It looks like you have fglrx loaded in addition to vga/vesa console and the kms driver.

The vga= option is not valid with any native framebuffer drivers it's a vesa option.  When kms is active, it controls the hardware directly rather than the vga console driver. If you want to specify a mode, use something like: video=1280x1024-24@60, etc.
Comment 14 Jerome Glisse 2011-03-07 12:05:33 UTC
Closing as this is most certainly a user configure issue, please properly remove flgrx, don't build ati framebuffer and don't use vga option, instead use videomode option thought by default kms should pickup an high resolution.
