User-Agent: Mutt/1.5.11+cvs20060126 Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi! I tried running few instances of while true; do echo 0 > /sys/devices/system/cpu/cpu1/online; echo 1 > /sys/devices/system/cpu/cpu1/online; done in paralel. It works okay, but, unfortunately, it provokes strange failures while trying to build kernel from another console: CHK include/linux/version.h SYMLINK include/asm-arm/arch -> include/asm-arm/arch-pxa make: Makefile:315: fork: Interrupted system call 1.88user 0.78system 11.20 (0m11.206s) elapsed 23.81%CPU pavel@amd:/data/l/linux-z$ CHK include/linux/version.h SYMLINK include/asm-arm/arch -> include/asm-arm/arch-pxa make: Makefile:315: fork: Interrupted system call 1.75user 0.72system 6.57 (0m6.578s) elapsed 37.64%CPU pavel@amd:/data/l/linux-z$ CC fs/dnotify.o make[1]: vfork: Interrupted system call CC kernel/uid16.o CC security/commoncap.o CC ipc/shm.o CC crypto/api.o CC crypto/scatterwalk.o LD security/built-in.o CC kernel/kallsyms.o LD ipc/built-in.o make: Makefile:876: fork: Interrupted system call 40.89user 8.60system 102.10 (1m42.101s) elapsed 48.48%CPU pavel@amd:/data/l/linux-z$ CC crypto/cipher.o CC crypto/digest.o Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
