Graphics hardware is NV250 type card.
Some quick testing last night showed this patch fixed both the boot messages and graphics performance. [tip:x86/urgent] rbtree: Undo augmented trees performance damage and regression http://marc.info/?l=linux-kernel&m=127833440902862&w=2

hrmpf, one of those wonderful messages where neither it nor its source code give you any clue regarding what caused it nor how to fix it.
please, apply this:
--- a/arch/x86/mm/pat.c~a +++ a/arch/x86/mm/pat.c @@ -359,7 +359,7 @@ int free_memtype(u64 start, u64 end) entry = rbt_memtype_erase(start, end); spin_unlock(&memtype_lock);
- if (!entry) {
- if (WARN_ON(!entry)) {
printk(KERN_INFO "%s:%d freeing invalid memtype %Lx-%Lx\n", current->comm, current->pid, start, end); return -EINVAL;
and let's at least see where it's coming from.
Not sure if its related, but also have a noticeable performance issue with graphics under rc4. Dragging and resizing windows, screen updates, and jumpy cursor are all slow. Playing a full screen video under vlc gets only 1-2 frames per second, but plays fine under rc3. Tested a kernel compile, it was roughly the same. Userspace is ubunutu 10.04 64bit.
Any hints? Otherwise will start a bisect tomorrow night.
Config attached, lspci, rc3 and rc4 boot messages below:
What graphics hardware are you using?
