Irix OS time and date are Snaphat RTC, not L1.

You won’t be able to straight boot to a new L1 RTC, you have to go through the-init of serial and default NVRAM values again (should be automatic). 

Try a soft-reboot after you stalled out on first boot.  At least on Fuel the first blank NVRAM step will result in error and reinit of default values, second boot actually uses default values.  You have to “double tap”, two boots to reinit a default L1 RTC then use it.

Also I’d you have special NVRAM values, you were supposed to use printenv to copy down all values and then set them up again yourself.  There’s no hot swap of RTCs so no way to transfer values.

If you lost resolution setting back to default, that’s normal. It was all stored in L1 RTC NVRAM.

Well getting a unreasonable date error when in single mode, so guess that's the Snaphat.. Will have to wait till the end of the week to get it sorted.
