It indeed works, however I still think there is a problem. 64-bit kernels should also boot when dropping -march=loongson2e. Also after adding the Loongson-specific integer instructions, I am able to boot a 32-bit kernel built with -march=loongson2e, but not a 64-bit kernel. -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurel...@aurel32.net http://www.aurel32.net
