Hello, This problem (and it's fix) is *not* PPC64 specific. The exact same problems occur on 32 bit powerpc platforms, and remain unaddressed. Accordingy, I've reopened this bug.
I've rebuilt the powerpc configured kernel with CONFIG_RTC_DRV_PPC=m. I added it to the initramfs, and loaded it at boot. This resolved the issues with setting the hwclock. Please apply CONFIG_RTC_DRV_PPC to all powerpc configurations. Thank you. Matt
