Hi ! Gerrit Binnenmars pointed out that others have the same problem: http://linux.omap.com/pipermail/linux-omap-open-source/2007-April/009535.html: http://article.gmane.org/gmane.linux.distributions.gumstix.general/21376/match=gumstix+realtime+bug+sched+c
Jan Altenberg showed me that in include/asm-arm/system.h I should comment out this line: #define __ARCH_WANT_INTERRUPTS_ON_CTXSW Without this line, irqs are disabled on context switches. But this is only a change that the WARN dose not more occure. Is this now a hack or the sollution? Hopfully some RT hacker can look deeper, and find what is wrong. thanks regards manfred Am Freitag, 20. April 2007 15:26 schrieben Sie: > hi jan ! > > Am Freitag, 20.
