Package: linux-image-4.9.0-8-amd64 Version: 4.9.144-3 Severity: critical Justification: breaks the whole system
Dear Maintainer, after installing the kernel updates that got released to Debian stable earlier today or yesterday, we saw all the three updated systems fail in the same way: after 3-5h, they stop responding. We managed to grab a picture of the kernel console on one of them, which showed a kernel panic in the IPv6 stack: https://imgur.com/7Teb8BV The topmost stack items are (hoping I got no typos) __pskb_pull_tail ip6_dst_lookup_tail _decode_session6 __xfrm_decode_session icmpv6_route_lookup icmp6_send That system was using the kernel this bug is reported against (linux-image-4.9.0-8-amd64 4.9.144-3). The other two affected systems used a backports kernel instead (linux-image-4.19.0-0.bpo.2-amd65 4.19.16-1~bpo9+1). Unfortunately we have no console access there, all we can do there is a hard reboot from the web interface. These servers are all operating as gateway servers for our Freifunk network, meaning they mostly forward traffic and their network setup is very non-standard. Please let me know if there is any configuration details that would be helpful to track this down. Kind regards, Ralf
