Andi, I noticed these on my AMD64 box earlier. Just a warning or anything to be concerned about ?
What happened with this one? Looks like a bug in the vesafb code. Do we know if it is fixed in 2.6.13-rc4? (Badari is on leave - could one of the fbdev developers please help out?) Thanks.
Thanks,
Badari
