Wheezy on laptop
The installation of "Testing" on a laptop runs fine. After the first boot appear only a few lines and the screen becomes dark. The only tool to stop is the power-switch. Tests over a few month with different releases had the same result. The same releases on other PC's work fine. "Stabel" (Sqweeze) on the mentioned laptop too.
The laptop: emachines E725 with Pentium(R) Dual-Core CPU and Broadcom BCM 4312.
I do not know if that effect is already known and what to do.
