Thanks for the report. 👍🏻

I think this could be viewed as a sub-problem of #5767. Any fix for #5767 needs to handle this test case also. I'll cross-post there.

Re-opening as I'd like to refocus #5767 to the KW_ONLY sentinel. Keeping this to track the issue of kw_only reordering the positional and keyword arguments needed for the dataclass constructor.

Happens with the kw_only parameter of dataclasses.field too:

"""Quick test to demonstrate pylint errors when using kw_only dataclass
fields."""
from dataclasses import dataclass, field

@dataclass
class Creature:
    """Defines a creature with one or more names (first names, middle names,
    last names, etc.)"""
    names: list[str] = field(kw_only=True)

@dataclass
class Human(Creature):
    """Defines a human who has a home address."""
    address: str

donna = Human('1858 Hidden Meadow Drive, East Grand Forks, ND 56721',
              names=['Donna', 'Jennings'])
print(donna)

I posted a fix to astroid for this. Most issues with kw_only should be resolved with that PR.
