OK! I have not tried to create patches using this method, but will try it. > The 2.6.35 kernel > source no longer compiles with SMP turned off unless it is patched and > I experience lockups on my single core CPU unless I turn SMP off. Very interesting. I have been building all my kernels with SMP disabled. To wit, Here are the relevant config options in my .config file for 2.6.38 (Mainline kernel), which I am now running: # # Automatically generated make config: don't edit # Linux/i386 2.6.38.0-1 Kernel Configuration # Wed Mar 16 23:19:36 2011 # # CONFIG_64BIT is not set CONFIG_X86_32=y # CONFIG_X86_64 is not set CONFIG_X86=y . . . # # General setup # CONFIG_EXPERIMENTAL=y CONFIG_BROKEN_ON_SMP=y . . . # CONFIG_SMP is not set Cheers, JD -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
