Created attachment 305916 [details] dmesg Kernel: 6.7.6 from openSUSE Tumbleweed (but I noticed it happening earlier as well, not sure since when) Network card: Bus 002 Device 005: ID 0b95:1790 ASIX Electronics Corp. AX88179 Gigabit Ethernet Reproducible: Happens maybe once a day or few days. Don't know how and why. Symptoms: Firefox stops being able to make any network connections. I need to kill it, because it's stuck even when closing. Everything else seems to be working fine (including stuff like https://github.com/debauchee/barrier).

I also encountered this bug. (division by zero in tcp_rcv_space_adjust) I am using Arch Linux with vanilla kernel. I think it started happening when upgraded when I upgraded from kernel 6.5.7 to 6.6.1 but was definitely around when I upgraded to 6.6.5 based on the Firefox crash reports I have. It can also happen to slirp4netns when running with rootless podman. However, this is definitely adapter dependent. I have two USB AX88179 Gigabit Ethernet devices. It only happens with my old Trendnet TU3-ETG v1.0R but I got a new Tp-Link UE300C and I have not encountered this issue at all. The old Trendnet device was acting weird even before this bug. For example, it only worked with certain USB ports.
I can confirm same issue and same hw ASIX AX88179. ciao luigi
I think this might have been resolved. I haven't had this problem for some time.
