I tried to reproduce this with no luck: $ mv hugh .config $ make scripts/kconfig/conf -s arch/i386/Kconfig * * Restart config... * * * Power management options (ACPI, APM) * Power Management support (PM) [Y/n/?] y Legacy Power Management API (DEPRECATED) (PM_LEGACY) [N/y/?] n Power Management Debug Support (PM_DEBUG) [N/y/?] n Suspend to RAM and standby (SUSPEND) [Y/n/?] (NEW) n <= I selected 'n' Hibernation (aka 'suspend to disk') (HIBERNATION) [N/y/?] (NEW) n <= I selected 'n' * * Fusion MPT device support * Fusion MPT ScsiHost drivers for SPI (FUSION_SPI) [Y/n/m/?] y Fusion MPT ScsiHost drivers for FC (FUSION_FC) [N/m/y/?] n Fusion MPT ScsiHost drivers for SAS (FUSION_SAS) [N/m/y/?] n Maximum number of scatter gather entries (16 - 128) (FUSION_MAX_SGE)  128 Fusion MPT misc device (ioctl) driver (FUSION_CTL) [N/m/y/?] n Fusion MPT logging facility (FUSION_LOGGING) [N/y/?] (NEW) # # configuration written to .config # CHK include/linux/version.h CHK include/linux/utsrelease.h make: *** [_all] Interrupt $ grep HOTPLUG_CPU .config # CONFIG_HOTPLUG_CPU is not set If you let kbuild do a silentoldconfig then I expect it to be set due to SUSPEND being set. If you can still reproduce it could you then explan the exect stepts to do so. PS. I used latest -linus as of yesterday.
