Ah. Now I'm with you.
I wonder whether you'll get better help by talking to the guys who
really understand the memory manager. They're accessible via the
Linux-MM mailing list, which I've cc'd.
Guys, Chun-mok is using a 2.4.19-rmk7-pxa2 kernel. Are you able to give
him some suggestions?
Regards,
Nigel
