Hi,

KMS with radeon driver doesn't work properly using the svideo output connected
to a CRT TV.

See startup with and without KMS :
http://aprovin.linux62.org/others/forums/kms/startup_with_kms.mp4
http://aprovin.linux62.org/others/forums/kms/startup_without_kms.mp4

I tested with 3.2, 3.1, 2.6.39, 2.6.32 kernels. The bug is present.

Because of this bug, it's impossible to use a X session (color and resolution
corrupted).

I built a custom kernel (3.2.2) with debug flags enabled for radeon driver. See
the dmesg.

If you need others informations or I test a patch, I'll do it with pleasure.

Regards,

Aurélien PROVIN
