It's the same grub, same video mode as before the regression, so the size is probably 0x300000 like it always was. > a r8g8b8 pixel format with resolution 1024x768 should be correct. Since is > 1024 * 768 * (24 / 8) = 2359296 = 0x240000. That is internally consistent, but at variance with the video mode set up by grub. It is better to sqeeze bits by 4:3 on each line (regression) than to scatter 4 logical lines across 3 physical lines (regression, patched) ! > Could you please apply the following diff that will print all the relevant > fields from the screen_info that are used to calculate the bpp and stride. YES ! I can't peer into that struct screen_info and I don't know to write the printk's. (Hm, doesn't look too hard, but trust me, I would fumble it.) I'll back out the original patch first. Stand by. --PA
