I agree this is not a driver issue. After I change many BIOS setting and restore BIOS to default. Finally I reproduce the X1 Carbon 5th with PCIID 1577/1678/15d6.
Actually I don't know how exactly reproduce this issue, only 2 times reproduced. When the failure happened the PCIID 1577/1578/15d6 shown that instead of 15d3. And thunderbolt driver loaded with call trace, suspend will make system hang. ** Attachment added: "x1carbon5th-1577-dmesg.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1708043/+attachment/4932133/+files/x1carbon5th-1577-dmesg.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1708043 Title: Lenovo X1 Carbon Gen5 fails to resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1708043/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
