  Newtonian gravity predicts the existence of white dwarfs with masses far
exceeding the Chandrasekhar limit when the equation of state of the degenerate
electron gas incorporates the effect of quantum spacetime fluctuations (via a
modified dispersion relation) even when the strength of the fluctuations is
taken to be very small. In this paper, we show that this Newtonian
"super-stability" does not hold true when the gravity is treated in the general
relativistic framework. Employing dynamical instability analysis, we find that
the Chandrasekhar limit can be reassured even for a range of high strengths of
quantum spacetime fluctuations with the onset density for gravitational
collapse practically remaining unaffected.
