Why is this a regression ? Thanks, tglx

Mirco? Indeed. As it happened only once. I've tried to reconstruct the circumstances that triggered it, but wasn't able to see it again. So I assume it was some weird hardware problem atm. Will observe further though.

Mirco? This is an informational warning which is new. That's not a BUG or in any way creating trouble. We have ignored the BIN mode bit for 15 years in Linux due to hardcoding ALWAYS_BCD=1 which removes all the BIN mode pathes at compile time already. The reason for this WARN_ON was to gather information whether there are any machines which have the RTC configured in BIN mode. This particular machine showed the BIN mode flag once and it looks like a hardware glitch. Thanks, tglx
