The address 07200720 looks like a couple of gray spaces in a vga console
and I've seen that before not long ago.
After a bit of searching, I've found it: it's in the thread that started
with "Linux 2.6.35-rc2", and most importantly in the thread:
BUG kmalloc-4096: Poison overwritten (2.6.35-rc2)
where there is a patch that is supposed to fix this. I thought this was
already applied upstream, though...
For your convenience, the patch in that thread is this one (might be
white space mangled, as I just copy+pasted it, so you might need to
apply it by hand):
