[PD] pd-0.38-4 / kernel 2.6 / scheduling / lockups

[=?X-UNKNOWN?Q?g=FCnter_geiger?=]

Hi,

Hmm, yes it seems that on newer systems the patch lacks an include.
You should have

#include <sys/mman.h>
#include <sys/resource.h>

somewhere at the top of s_inter.c. (The sys/resource.h is missing in
the patch)...

About the fixing of latency stuff I don't know. I very seldom have latency
problems, because I don't do disk I/O or video together with sound on one
machine.

Greetings,

Guenter
