My Lenovo 3000 G530 laptop had 3 ( 2 + 1 ) GBs of memory and I upgraded ram to 4 ( 2 + 2 ) gigs and it does not boot after then. - System boots to grub successfully. - installed kernels ( 3.5.x desktop/default/vanilla, 3.1.x desktop/default/vanilla ) computer resets in seconds. - failsafe kernels also reset the computer. - There is not any weird messages in screen before rebooting. - System boots normally with single module or any setup with 3 GBs in total. - I updated the BIOS to latest version. - I checked memory modules via memtest and no error reported. - My system has dual boot with Win7 64 Bit and it works perfectly. So I am absolutely sure that hardware is good. - Also failed to boot with; -- OpenSuSE 12.1 64 Bits Net Install CD -- OpenSuSE 10.2 64 Bits DVD - I tried to boot OpenSuSE 64 Bits CD/DVD's and my installed kernels with these options, but no success... -- acpi=off -- acpi=force -- pci=noacpi -- acpi=oldboot -- apm=off -- ide=nodma -- edd=on -- edd=off -- noapic -- nolapic - I have a large collection of dists, I successfully boot with; -- gentoo 64 Bits CD -- gentoo 32 Bits CD -- OpenSuSE 10.3 32 Bits DVD -- OpenSuSE 11.4 32 Bits DVD -- System Rescue CD 64 Bits -- System Rescue CD 32 Bits -- Ubuntu 11.4 64 Bits DVD I tried to identify the problem and diff Ubuntu kernel config with OpenSuSE kernel config. At the end; found a solution (attached kernel config diff file). After compiled some custom configured kernels i found that i could boot with these kernel options; CONFIG_ACPI_PROCESSOR=y (this one automatically sets CONTAINER and THERMAL to YES) CONFIG_ACPI_CONTAINER=y CONFIG_X86_ACPI_CPUFREQ=y CONFIG_THERMAL=y I also tried to add these kernel modules to initrd and made these tests; Test 1 - opensuse desktop kernel - reboots sysconfig -> initrd_modules = processor container acpi-cpufreq thermal_sys Test 2 - opensuse desktop kernel - reboots sysconfig -> initrd_modules = thermal processor fan container acpi-cpufreq thermal_sys Test 3 - opensuse desktop kernel - reboots sysconfig -> initrd_modules = processor fan container acpi-cpufreq thermal_sys Test 4 - opensuse desktop patched kernel - BOOTS & RUNS OK sysconfig -> initrd_modules = thermal processor fan And tried a semi-patch as; CONFIG_ACPI_PROCESSOR=y (this one automatically sets CONTAINER and THERMAL to YES) CONFIG_ACPI_CONTAINER=y CONFIG_X86_ACPI_CPUFREQ=M CONFIG_THERMAL=y Test 5 - opensuse desktop semi-patched kernel - BOOTS then REBOOTS after starting BOOT daemon sysconfig -> initrd_modules = thermal processor fan Test 6 - opensuse desktop semi-patched kernel - reboots sysconfig -> initrd_modules = thermal processor fan acpi-cpufreq IN SHORT; These settings works in both 3.1.X and 3.5.x kernels for me; CONFIG_ACPI_PROCESSOR=y (this one automatically sets CONTAINER and THERMAL to YES) CONFIG_ACPI_CONTAINER=y CONFIG_X86_ACPI_CPUFREQ=y CONFIG_THERMAL=y I read there are some people reporting problems like opensuse DVD not boots but Ubuntu DVD works etc.. And i think these are pretty safe flags and we should use these while building opensuse kernels. Reproducible: Always Steps to Reproduce: 1. Boot system with 4 GB ram 2. In the grub select any kernel (3.5.x desktop/default/vanilla, 3.1.x desktop/default/vanilla) 3.
