>Synopsis: amd64 system kernel panicking multiple times per hour - appears >networking related >Category: bug >Environment: System : OpenBSD 7.4 Details : OpenBSD 7.4 (GENERIC.MP) #1397: Tue Oct 10 09:02:37 MDT 2023 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64 Machine : amd64 >Description: System kernel panics with the following error: panic sbdrop db_enter() at db_enter+0x14 panic(ffffffff820d627c) at panic+0xc3 sbdrop(fffffd83b292f990,fffffd83b292fab8, 7f) at sbdrop+0x23f tcp_input(fff8000180fb488, fff8000180fb494, 6, 2)) at tcp_input+0x2416 ip_deliver(fff8000180fb488, fff8000180fb494, 6, 2) at ip_deliver+0x113 ipintr() at ipintr+0x69 if_netisr(0) at if_netisr+0xc0 taskq_thread(ffff80000002f200) at taskq_thread+0x100 Screen picture here: https://ibb.co/Lrrqd3S Unfortunately ddb would not respond so I was unable to capture the full trace for the other 3 CPUs. I have rebooted the machine and will try again next time this happens. >How-To-Repeat: Currently this happens again within about 20 mins of bringing the machine back online. This machine has been running fine on 7.3, but after upgrading to 7.4 yesterday this has been happening consistently. >Fix: Unsure. dmesg: OpenBSD 7.4 (GENERIC.MP) #1397: Tue Oct 10 09:02:37 MDT 2023
