Whenever I boot my laptop, I see this message and it makes the boot process very slow as my screen stays black for a long time before this message appears. It shows just for a split second but today It got worst when my system couldn't boot and stuck on this error, I did several reboots but still couldn't pass this boot error message, then after sometime it fixed itself and now I can use my system as normal.

I didn't pay much attention to the error when It was there for just a split second and making my boot process slow, but now that it has stopped me from booting into my system, I would like to know why this error occurring.


...failed to get i915 symbols, graphics turbo disabled....

Posting here the workaround suggested in the launchpad discussion:

add intel_ips to the blacklist:

echo "blacklist intel_ips" >> /etc/modprobe.d/blacklist.conf

add i915 and intel_ips to /etc/modules:

echo -e "i915\nintel_ips" >> /etc/modules

Workaround has caused errors too as detailed in the Launchpad discussion - [drm:i915_init] ERROR drm/i915 can't work without intel_agp module! FWIW I have not had the issue when running Natty Alpha 2 on a live usb. – Mark Rooney Feb 13 '11 at 11:02
