I was in the midst of doing my python-update to 2.5 stable when some gnome package barked at me to make a fresh kernel so 2.6.26 seemed a good route to avoid needing to mess with that system for a couple weeks. After configuring the kernel with a few minor adjustments and making the image i sat in anticipation awaiting good results however this error i've never witnessed materialized.

I'll offer that i'm certainly not an amateur with configuring and building kernels by hand after building a thousand or so gentoo systems in three or four years but you always run into something new so it said to debug make... hey sure lets see what it's griping about

I'm fairly certain that vdso is quite important to the proper function of the kernel's resource addressing. I only let make run until the first two errors materialized however the image compile will complete. The completed image make doesn't always guarantee favorable results with warnings. Anyone have any thoughts? |
