Hi,

just a random question to rule things out: can you check if laptop mode
is enabled? (see the /proc/sys/vm/laptop_mode file). Laptop mode will
have the effect of grouping writes together, so if that got enabled
accidentally for some reason, that could explain the behavior you are
seeing. (and it would narrow down the "what broke" search problem to
something that is a lot easier to work on)
