Full panic trace recovered from EFI pstore (attached). The crash is in the GRO receive path of the Intel WiFi driver, not Docker as initially suspected:
RIP: skb_pull+0x40/0x50 skb_gro_receive_list -> tcp_gro_receive -> tcp4_gro_receive -> inet_gro_receive -> dev_gro_receive -> gro_receive_skb -> ieee80211_rx_napi [mac80211] -> iwl_mvm_pass_packet_to_mac80211 [iwlmvm] Comm: irq/166-iwlwifi, Dell Latitude 3420, BIOS 1.44.0 Docker merely generates the burst of inbound TCP-over-WiFi traffic that triggers it. So this looks like TCP GRO list handling breaking on mac80211/iwlwifi received frames in 7.0.0-27. ** Attachment added: "dmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2159646/+attachment/5980416/+files/dmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2159646 Title: kernel BUG at include/linux/skbuff.h:2833 — 100% reproducible panic ~20s after boot when Docker restarts a container (7.0.0-27-generic) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2159646/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
