awk - BASH append line to earlier line if preceded by spaces -

i have file looks this:

t2_this_is_some_output_80_pool             address 12.34.56.78             state down             address 13.34.56.78             state down t2_this_is_a_different_output_80_pool             address 14.34.56.78 t2_this_is_another_output_80_pool             address 15.34.56.78             state     

i wnat output looks like:

t2_this_is_some_output_80_pool address 12.34.56.78 state down t2_this_is_some_output_80_pool address 13.34.56.78 state down t2_this_is_a_different_output_80_pool address 14.34.56.78 t2_this_is_another_output_80_pool 15.34.56.78 state 

i've been trying bash, awk , sed, nothing have done has been able give me output need it.

one of things i've tried:

replace 12 spaces @ beginning = append previous line if line starts =

cat file.txt | sed 's/            /=/' | sed -e :a -e '$!n;s/\n=/ /;ta' -e 'p;d' 

but that's not working...

any received :-)
