It's not necessarily a kernel bug. The issue is that *either* the ac_adapter module needs to be loaded explicitly by the init scripts *before* fsck is run, *or* the ACPI and ac_apater modules need to be explicitly configured as being built into the kernel, i.e.:
CONFIG_ACPI=y
CONFIG_ACPI_AC=y
So this can be fixed in the kernel config file or by having the init scripts load the acpi and ac modules early.
