Date: Wed, 13 Jan 2010 20:51:31 +0200 From: Ozan Çağlayan <ozan@...dus.org.tr> To: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Subject: Boot hangs after "Freeing initrd memory" with 2.6.31.11 Hi, A lot of our users complains about the problem in $subject. Here are some clues: - All users have mainboards with nForce2 chipset: nVidia Corporation nForce2 IGP2 [10de:01e0] (rev c1) - The last working kernel for them is 2.6.30.9. They can't boot into 2.6.31.9-11, - They all tried several boot parameters to disable acpi, lapic, mce, etc. none of them works, - Their last working kernel (2.6.30.9)'s all shows some suspicious stuff: [ 0.000000] Using APIC driver default [ 0.000000] Nvidia board detected. Ignoring ACPI timer override.

I wanted to know how should I help them debugging the issue (except bisect because that would be a tough task for them). What should I interpret from a hang just after freeing initrd memory? They can't even reach the busybox in the initramfs so I can't suspect the initramfs code for now. Note that I've done two radical configuration changes from 2.6.30->2.6.31: Building AGP drivers and libata driver into the kernel image.
