I try to patch (also had to test latest stable release, to make sure it is appearing on it), and each test taking 1 day. If i "restart" script to resetup HFSC - it works for a while fine. At next day, peak time period - it goes wild. There is another thing also, i am going to try now, old kernel was 64-bit, but now 32bit, so i will try to shift to 64bit again. It can be not regression, but a bug. I guess not many people use HFSC, even it is definitely better than HTB.
