Down when i get date from rtc by "hwclock --hctosys"

[Bhupender Saharan]

Hi Leo,

Looks like your system is unstable when the cache is enabed. It might have
nothing to do with generic RTC driver.

Can you run cachebench or another memory benchmarks tools on the system and
see if memory sub system is OK.

Bhupi
