This looks the same as bug 1780076 which was closed because it didn't happen for long time. I think now we can keep this bz for the issue. Upstream fix: https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/commit/5e8c64d092e85f6d5479675499463464e1a42de6 Cannot see this particular crash anymore. marking as verified. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory (ModemManager bug fix and enhancement update), and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2021:4362 |
