I'm unaware of that; the only area of weakness with kexec that I'm aware of is when the ARMv7 processor support didn't implement the necessary code to bring the caches/mmu/tlbs into a safe state for software-reboot, which is also what's required by kexec. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
