If I remove 'ip router isis', IS-IS IPv6 does not work.
Have you seem this?
I confirmed that only IPv6 are enable on R1 and R4, entered 'no adjacency-check'(just to be sure it was not the cause, although there is no logic), but no lucky.
Tests with 'ip router isis' and 'ipv6 router isis':
Rack2R1#sh ipv6 route
I1 2001:148:5:4::/64 [115/20]
via FE80::230:94FF:FED8:FDE0, Serial0/0.14
L FE80::/10 [0/0]
via ::, Null0
C FEC0:148:5:14::/64 [0/0]
via ::, Serial0/0.14
L FEC0:148:5:14::1/128 [0/0]
via ::, Serial0/0.14
