Hello,

I have a bug (100 % repeatable) that prevents booting Linux when systemd is used as an init system. However, booting with traditional init works fine. I'm posting this bug to the DRI subsystem because I was (barely) able to capture to capture kernel message before the screen becomes blank. I can verify that this problem happens in all 3.11.x kernels and in Debian's 3.10 kernel. The hardware is Dell Vostro 3560 - Intel Ivy Bridge, hybrid graphics (Intel + Radeon), OCZ Vertex 4 SSD. My suspicion is that maybe the system bootup is too fast for the kernel; I was able to boot kernel once even with systemd, but that was when I turned on all the debugging messages which flooded console a bit.

Kind regards, Adrian
