Since commit 92b004d1aa9f367c372511ca0330f58216b25703 : prevent use of logs after they have been freed, my i915 machine has no logo on boot (reverting that commit brings it back on recent trees). My .config builds nothing but wireless as =m, so I think this is a genuine false positive (as predicted by the commit). Examining an augmented dmesg, it appears that the framebuffer setup is too slow by about 0.3s, which I wouldn't really expect from this system/driver. Is this slowness considered worth fixing, or is this issue considered too cosmetic? (Or is this just PEBKAC?) Possibly useful information: $ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) >From various printk()s, it looks like the slow portion of fb_console_init() is restore_fbdev_mode(), specifically drm_mode_set_config_internal(), which takes about 0.45s, while the fb_logo_late_init() call happens about 0.15s into that. I can give the full details if requested.
