Hello, I have been playing with v7 since your sending and after a white (short on laptop, longer on desktop, a few hours), writeback doesn't seem to work anymore. Manual call to sync hangs (process in D state) and Dirty value in meminfo gets growing. As previous versions had been heavily tested, I guess there is some regression in v7.
