[Xenomai-core] Bug in Linux kernel 2.6.37 blocks xenomai threads
Hi, there is a bug in kernel 2.6.37 (fixed in 2.6.37.1, see commit 1cdc65e1400d863f28af868ee1e645485b04f5ed) which blocks RT threads during creation. They stick to a certain CPU core for a certain amount of time (sometimes minutes ...) before they are migrated to the proper core and run as expected. Philippe, Gilles, maybe you could generate a new i-pipe patch based on the newest 2.6.37-series kernel. I patched a 2.6.37.6 kernel with adeos- ipipe-2.6.37-x86-2.9-00.patch and the problem was gone. -- Sebastian ___ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core

Ok, I'll handle this. I have some patches from Jan which have been pending for too long in my tree to add to this one. -- Philippe. ___ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
