All: I seem to be able to relatively reliably panic a system when using kexec to reboot. This does not happen during a normal boot sequence. Unfortunately, the stack trace I get for the panic is not consistent. I've included a few here. Mostly they seem to center on what smells like some sort of memory corruption to me. I'm kind of banging my head against the wall with this, so any help would be greatly appreciated. I have noticed, that I consistently get these messages when rebooting with kexec, but not when going through the normal system boot process: [ 4.961700] ACPI Exception: AE_AML_PACKAGE_LIMIT, Index
