What is reasonable depends on what you expect to be able to do with the
solutions. Numerical evaluation should be easy, but if you want canonical
forms (minimal polynomials) or the ability to check equalities, that's
going to be far more costly.
It looks like the eigenvalues of this matrix will

Arbitrary-precision computation of Bessel function zeros will be
provided in the next version of mpmath. See
