This seems to happen on every boot, though it doesn't prevent using the machine. Apport just happens to notice the error, I wouldn't have.

[Seth Forshee (sforshee)]

Timo,

It looks like the vesafb driver is getting some garbage values. I built a kernel with some additional logging to help track down where the bad values are coming from. Please install the packages from:

  http://people.canonical.com/~sforshee/lp772042/

After rebooting, capture the output from dmesg and attach it here. Thanks!

[Timo Aaltonen (tjaalton)]

ok here goes

[Seth Forshee (sforshee)]

It looks like the kernel is getting garbage data when querying the bios for video parameters via the vesa bios extensions. The bios indicates the maximum amount of framebuffer memory is nearly 4GB and that for the selected video mode the framebuffer size is nearly that big as well. The warning happens when vesafb tries to create an outrageously large memory mapping for the framebuffer based on these parameters.

Can you check whether there are any bios updates for your machine? If not I can look into creating some sort of workaround.

[Seth Forshee (sforshee)]

If you can't fix your problem with a bios update, I think I have a workaround for you. Add this line:

GRUB_GFXPAYLOAD_LINUX=text

to /etc/default/grub and then run 'sudo update-grub2'. Afterward you won't get the smooth graphical handoff from grub to the kernel, but it should also stop them from using vesa graphics during boot, which should get rid of the warning.

[Timo Aaltonen (tjaalton)]

Yep, that works. There is only an update to the WOL function, so didn't bother testing the new bios.

[Timo Aaltonen (tjaalton)]

oh and actually, I need that workaround to get functional VC's, so this system is probably a candidate to the blacklist?

[Seth Forshee (sforshee)]

Adding it to the blacklist makes sense to me. Adding a grub task and marking the linux task invalid.

[dino99 (9d9)]

Natty is no more a supported version; and grub legacy upstream is also stopped, only receiving possible random fixes locally
