[SunRescue] Bit Error in TOD Clock

[Mike Nealey]

Hi Harry,

I hate to do a "Me too" but, me too! I replaced two NVRAMS in some sparc2's and I
am havinf the same problems. If you just leave them running everything is fine,
but if you turn them off you must lay on hands to boot them again.

If anyone has a fix, I'd love to hear it!

Mike N.
