Description Dennis Schridde 2013-02-22 20:33:36 UTC 
A vanilla 3.7.9 kernel, compiled with gcc-4.7.2, linked with binutils-2.22-r1, fails to boot on my HP rx2600 ia64 machine. After elilo loaded the image, nothing happened, and the system rebooted automatically after a while.

Earlier, I tried to build versions 2.6.32-r116, 3.2.34-r2, 3.2.35, 3.7.0 of sys-kernel/hardened-sources using sys-devel/gcc-4.6.3 and while the build succeeded, the resulting kernel images did not boot, either.

Please assist me in acquiring more information, as there currently is no output at all on the serial console I am attached to (via the management console, which is set up in EFI as the default console, which appears in Linux as ttyS3). Usually I get output right from the start, so I assume that the problem must be very early in the boot process.

Config, System.map, vmlinuz all available at:

So, from what I understand, you're running Gentoo.

Well, me too on a zx6000 workstation, so very close to your rx2600. And I have no problem booting sys-kernel/gentoo-source-3.12.13 compiled with sys-devel/gcc-4.7.3-r1. So, would you please try my attached .config with your rx2600 server and tell us if it works or not?

From my .config file, you can probably disable zx1 AGP GART support and Audio support as I imagine that your rx2600 is in stock configuration with a PCI-X-only cage (no AGP slot) and no sound card. If you don't have a Radeon graphics adapter either, change for your graphics card model as well. Last, I'm running systemd rather than OpenRC, so you may also have to alter this.

Hope this helps,
