I'd like to play with the kernel's suspend-to-disk feature, so I'm trying to build a custom kernel using kernel-sourcecode-2.6.6-1.435.
When I enable either the CONFIG_SOFTWARE_SUSPEND or CONFIG_PM_DISK
power management options, the kernel build fails with with the following errors, respectively:
arch/i386/power/built-in.o(.text+0x1b4): In function `pmdisk_arch_suspend': : undefined reference to `swsusp_pg_dir' arch/i386/power/built-in.o(.text+0x263): In function `do_magic': : undefined reference to `swsusp_pg_dir' make: *** [.tmp_vmlinux1] Error 1
Any ideas? Other people have been discussing suspend-related stuff on this list, so I
imagine I'm doing something wrong.
p.s. Here are relevant lines from my kernel .config file:
# # Power management options (ACPI, APM) # CONFIG_PM=y CONFIG_SOFTWARE_SUSPEND=y CONFIG_PM_DISK=y CONFIG_PM_DISK_PARTITION="/dev/hda5"
