Enabling Avahi or UPnP crashes firewall

  • Trying to enable Avahi (running 2.5.0.a.20200210.1039) crashes the firewall.

    Also happens when I try and enable UPnP.

    That is a very, very low level crash. Most likely in hardware. Maybe interaction with a driver, but if that were the case I'd expect to see the driver code somewhere in the backtrace. This is crashing in a fairly simple software interrupt processing call.

    If it's stable on 2.4.4-p3, there is a chance it's some interaction between the OS and your hardware/BIOS. Might try again after we move the base OS up to 12-STABLE in the near future.

  • Ok, I’ll wait as you suggest.

    It is working fine on 2.4.4-p3, both UPnP and Avahi.
