On the machine which has troubles, the bug occured within about 10 days During these days, the amount of dirty pages increased, up to 400MB. I have testet kernel 2.6.19, 2.6.20, 2.6.22.1 and 2.6.22.10 (with our config), and even linux-2.6.20 from ubuntu-sever. They have all shown that behaviour.

10 days ago, i installed kernel 2.6.18.5 on this machine (with backported 3ware controller code). I'm quite sure that this kernel will now fixes our severe stability problems on this production machine (currently: Dirty: 472 kB, nr_dirty 118). If so, it's the "lastest" kernel i found usable, after half of a year of pain.
Strange, my tests show that both 2.6.18(.8) and 2.6.19(.7) are OK and the first wrong kernel is 2.6.20.
BTW: Could someone please look at this problem? I feel little ignored and in my situation this is a critical regression.
