Description Cijoml Cijomlovic Cijomlov 2008-01-23 01:56:14 UTC

Latest working kernel version: config-2.6.22.5
Earliest failing kernel version: 
Distribution:Debian stable
Hardware Environment: Dell Optiplex GX620, BIOS A11 (latest)
Software Environment: Debian stable, Intel FB compiled into kernel
Problem Description:

When kernel boots I see normal letters on the screen until in-kernel-compiled-intelfb is inicialited. From that time my LCD's LED says "No signal" and I see nothink until Xorg starts. Then I can jump from Xorg to intelfb screen with ctrl+alt+f1 and nice fb is there. With my previous 2.6.22.5 this works.

Steps to reproduce:

boot kernel and look

Boot
