No switching to high-resolution fbcon occurs, screen freezes with 80x25 mode right before the switch (PCI bridge info in my case). Otherwise, box boots normally, allowing blind reboot. 6d86951a45013ac5b060c5e6307b11b7c685c76f is the first bad commit commit 6d86951a45013ac5b060c5e6307b11b7c685c76f Author: Ben Skeggs Date: Wed Dec 8 11:19:30 2010 +1000 drm/nvc0: initial support for tiled buffer objects Signed-off-by: Ben Skeggs diff --git a/drivers/gpu/drm/nouveau/nouveau_bo.c b/drivers/gpu/drm/nouveau/nouveau_bo.c index 5dc639e..74d0ef4 100644 --- a/drivers/gpu/drm/nouveau/nouveau_bo.c +++ b/drivers/gpu/drm/nouveau/nouveau_bo.c @@ -120,9 +120,6 @@ nouveau_bo_new(struct drm_device *dev, struct nouveau_channel *chan, align >>= PAGE_SHIFT;
