In the kernel I'm using (2.4.2-2) I've noticed that if you increase HZ above 1536 you get a conflict with .../include/linux/timex.h:75-77 and if you add some lines there, you get a problem with .../include/net/tcp.h:377 when HZ is above 4096. Is there an easy way to increase clock interrupt freq, or do I have to mess with the whole kernel ? Thanks in advance. Antonios
