Various people were worried about x86. Around version 15 I altered the patches so that they only impacted PowerPC. If they impact x86 in current form that is a bug. When x86 is ready for it I do think dynamic module loading should be implemented there also. > > -- > Jean Delvare > -- Jon Smirl [EMAIL PROTECTED] _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
