[Bug 710954] New: Core i5-2500K [Sandybridge] built-in Graphics fails since kernel update to 2.6.37.6-0.7
https://bugzilla.novell.com/show_bug.cgi?id=710954 https://bugzilla.novell.com/show_bug.cgi?id=710954#c0 Summary: Core i5-2500K [Sandybridge] built-in Graphics fails since kernel update to 2.6.37.6-0.7 Classification: openSUSE Product: openSUSE 11.4 Version: Final Platform: x86-64 OS/Version: openSUSE 11.4 Status: NEW Severity: Major Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: logicacmg@hayo.de QAContact: qa@suse.de Found By: --- Blocker: --- Created an attachment (id=444681) --> (http://bugzilla.novell.com/attachment.cgi?id=444681) XOrg log file User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:5.0) Gecko/20100101 Firefox/5.0 I have installed the standard security updates YaST2 Online Update has offered me. During this update the kernel updated from 2.6.37.6-0.5 to 2.6.37.6-0.7. Since then the screen gets dark immediately right after the first kernel screen outputs (usually hidden behind splash). Before that the system worked fine. I found out after a while, that it is possible to start the system nonetheless. My system is fully LUKS encrypted. The failure happens before the root system is available! Of course it is possible that my problem is caused by another component than the kernel, but as there is no downgrade option to really validate this, this is the best guess. Reproducible: Always Steps to Reproduce: 1. Buy a Gigabyte H67A-UDH3-B3 keyboard. 2. Buy a Intel Core i5-2500K (and install it). 3. Attach a 1920x1200 monitor via DVI-D to the mainboard. 4. Install OpenSUSE 11.4. 5. Install all patches provided until 2011-08-07 (esp. kernel 2.6.37.6-0.7). 6. Boot system. Actual Results: Usually it shows only the splash screen and then the screen turns black (no signal). If splash screen is removed by boot option, there is a screen output "doing fast boot" and very short time the next output line ("Creating device nodes with udev" in my case), then black (no signal). Expected Results: System should start with 1920x1200 resolution and start X11. Mind that the Xorg.1.log is written after the problem actually happened, because at that time the system definitely has no access to any other file system than /boot. Workarounds: - start failsafe. System runs in 1024x768, which is not feasible for real work. - start system with boot option nomodeset vga=0x34B This gives at least the opportunity to work with 1600x1200 -- 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.
