Title:
panic/lock/restart on dapper-amd64 if there's intel integrated video
This particular bug shows up repeatedly in various forms in the Ubuntu
and Mint forums. It prevents booting from CD on many, perhaps all Dell
or HP computer with onboard graphics where a PCI graphics card has been
added. Many of those computers are strapped with a BIOS that allows
disabling the
Same thing happens to me on a HP Pavilion a1106n with i950G Intel
Graphics and a nVidia GeForce 6200 PCI. I think the same thing happened
when I tried a PCI voodoo3, too.
Also I know that this happens to someone with a HP Pavilion a1000n and a
PCI NVidia Verto GeForce FX 5200 card. He also says
The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the
upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would
appreciate it if you could please test this newer 2.6.27 Ubuntu kernel.
There are one of two ways you should be able to test:
1) If you are comfortable
This still happens on latest feisty 2.6.20-x kernel, and the latest
module-init-tools upgrade renders the system unbootable, as it removes
the previous /etc/modprobe.d/blacklist file.

panic/lock/restart on dapper-amd64 if there's intel integrated video AND a
nvidia card at the same time
Update: it affects both 32 and 64 bit 2.6 kernels.
I noticed the bug happens with Edgy, Fedora 3, 4, 5 and FC6t1, a Gentoo
Derivative called Kororaa, Debian CDD-BR 1.0, Dapper and Breezy. It
happens with several different msi and intel boards.

I found out that this is not only nvidia and i865 related. Several intel
chipsets suffers from this issue, and using ATI boards makes the problem
appears as well. This makes the bug's relevance critical.
i945 shows the very same problem (which makes this one not being a
specific isolated case).
I suspect there's also a BIOS option to disable the built-in video, or
prefer the AGP slot.

Changing udev rules for nvidia or intel-agp would be the ideal solution.
As a simple fix, I did a script which checks if both hardware are
present and then I mount / as rw, blacklisting intel-agp and then I
mount / as read-only again (fsck expects this). It must be ran quite
early - before the
Ben, even if I disable the addon video chip (the boards I'm working on
this have all this setting and none of them works), the issue raises.
And the device is still present on the system. Broken bios, I know. As
there are some of those boards around, a fix is still needed.
One extra issue is that
Blacklisting nvidia still makes the machine lock.
