Hello, as already mentioned by Manish http://lists.infradead.org/pipermail/kexec/2008-August/002497.html physical_arch() is searching for the string to match "arm", but various ARM CPUs have additional letters to specify their features. Should all these types be listed in arches[] or is it simplier to have ARM speciifc physical_arch() that is just looking for the substring "arm" in uname? What do you think about this? Best regards, Yegor
