Documented at: http://tstotts.net/linux/gentooinsp640m.html#d3e1295a1900 With 2.6.22 the boot lock-up problems were even worse. Basically solved with 2.6.22 as follows: - any version of gensplash / bootsplash could lockup VESA on this machine if compiled-in - SLUB and full preemption seem to sometimes misbehave when initializing kernel state or hardware - VESA driver needs a very explicit mode to disable EDID and BIOS-based frequency changing - libata does better when loaded from initramfs than compiled-in -timotheus
