Right after beginning the installation (w/standard options), the system screen will flash and/or the system will halt (w/udev process failure). System can be installed w/ACPI=OFF but then no ACPI support is provided in the installed system (will not shut down, etc). Once an installation is completed with ACPI=OFF, removing the ACPI=OFF option from the resulting kernel boot parameters will result in the same behavior (flashing screen immediately after choosing boot option). This is quite easy to reproduce. This problem may be Ivy Bridge related. We have experienced this on a Clevo (Sager) P150EM laptop running BIOS versions 1.00.04 and 1.00.05. We have also tested this laptop with both the Nvidia graphics card option (Optimus) and also the AT Radeon option. Both systems experience identical ACPI problems regardless of the video card installed. Both Clevo and Sager are aware of this issue and state the problem is with the distro (of course). They claim the recent Ubuntu release installs and runs just fine... Reproducible: Always Steps to Reproduce: 1. Begin baseline install with OpenSuse 12.1 x86-64 distro 2. Select option for new installation (do not change options) 3. Screen will crash with a flashing screen or just hang (with udev process failure message) Actual Results: Screen will flash shortly after selecting "New Install". System might also hang (identifying udev process failure in background). (Installing with ACPI=OFF works around this problem.) Expected Results: System should install properly and ACPI functions should be properly supported. Clevo/Sager P150EM (Ivy Bridge) Laptop Confirmed on BIOS V 1.00.04 and 1.00.05 Confirmed by us and also Sager/Clevo Problem exists with both Nvidia (Optimus) and Ati Radeon Video Card Options -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
