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: _______________________________________________ kexec mailing list kexec@lists.infradead.org http://lists.infradead.org/mailman/listinfo/kexec
