These are TLB entries and TLB stands for "Translation Lookaside Buffer".
It's a table of relation of Virtual
Address range and Physical Address range that RISC processor uses.
"Invalid" in TLB entries does NOT indicate HW/SW failure. That indicate an address
region that CPU doesn't use.
In this case, "Invalid" address region are defined as follows.
TLB entries : 58

0x12000000:0x13FFFFFF 0x012000000:0x013FFFFFF CacheMode=2, RW, Valid

This is no problem.
