[Bug 542208] [NEW] Please blacklist i830 from Kernel mode-setting

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Please add i830 (8086:3577) to the kernel drm KMS blacklist.

Testing has shown that KMS support for the i830 chipset is inadequate,
often resulting in a regression where the system hangs during boot up.
While the issues have been reported upstream, solutions seem not soon
forthcoming.  Testers have found that booting with i915.modeset=0
generally tends to restore the system functionality.


[Original Report]
Dell C400 with Intel 82830 CGC, booting
lucid 2.6.32-16-generic causes screen to flash
several times and graphics are then hung
with blank screen and no cursor. No response
to ctrl-alt-F1. Backlight eventually turns off
and then comes back when Shift is pressed.
Remote login with ssh works OK.
