Another case I've seen where TCP checksum failed was in old Eee PCs. There, the TCP checksum check on incoming packets was offloaded to the network interface. Unfortunately, some Linux driver and/or hardware bug occasionally corrupted the packet payload after the check passed. The workaround was to disable the hardware check. https://www.tablix.org/~avian/blog/archives/2010/10/eeepc_notworking/ https://www.tablix.org/~avian/blog/archives/2010/10/eeepc_no...
