I was running v2.6.33-rc2-187-g08d869a and everything was ok. Today I
decided to update the kernel (to v2.6.33-rc4) and a minute or two after
logging into the gnome desktop this kernel bug appeared in dmesg. I then
went back to the old kernel but the bug didn't disappear, not even after
running btrfsck on the filesystem.
