[petsc-users] Multiple solves with PCMG fail

[Filippo Leonardi]

Sorry for the late update.

I tested the code with the branch:
ksp-zero-eig

But the problem seems to still be there, also tried:
-ksp_chebyshev_estimate_eigenvalues_random
but does not change.

Just tell me what test you need and I'll try to do them.

Best,
Filippo
