Bug 115620 – Dual Opteron crashing after grub with 2.6.14-gentoo-r4

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Stefan de Konink 2005-12-14 20:34:59 UTC]

After trying to build a new kernel based on my working 2.6.13-gentoo kernel
config. I ended up with a kernel who wasn't willing to boot. The old kernel does
boot. Attached are a 'screenshot' and the kernel config.

I'm going to try the vanilla sources too... incase this is a gentoo specific
problem.

Reproducible: Always

This is related to NUMA and SPARSEMEM. This patch should fix it for 2.6.14.
Please test.

The patch, manually applyed, works for me.

(To be honest, I see another odd long line too, directly after grub booting for
2.6.14 and 2.6.15, but I'm too slow to get it on photo. So maybe it is nothing,
just a ghostimage on CRT (like the kernel version), but better said than keep it
silent.)

Fixed in gentoo-sources-2.6.14-r5 (genpatches 2.6.14-6)
