@Shengyao Xue, 1.) Intel suspected that this Lenovo issue might be related to this issue: https://bugs.launchpad.net/somerville/+bug/1933807 on Intel vPro system. Lenovo did mention that vPro systems have the same issue.
2.) Intel SW debug engineer is adding some debug prints to the I219 runtime power managements callbacks to see if they are getting called, even though they shouldn’t. I will share patches once it is available. 3.) Can you please try below and see whether you can reproduce the issue? Please also pay attention if the system cannot enter Suspend to Idle after applying this. echo on > /sys/bus/pci/devices/0000\:00\:16.0/power/control Explanation, taken from https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-devices-power: What: /sys/devices/.../power/control Date: January 2009 Contact: Rafael J. Wysocki r...@rjwysocki.net Description: The /sys/devices/.../power/control attribute allows the user space to control the run-time power management of the device. All devices have one of the following two values for the power/control file: + "auto\n" to allow the device to be power managed at run time; + "on\n" to prevent the device from being power managed; The default for all devices is "auto", which means that they may be subject to automatic power management, depending on their drivers. Changing this attribute to "on" prevents the driver from power managing the device at run time. Doing that while the device is suspended causes it to be woken up. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1927925 Title: Massive network problems with I219-V on Thinkpad T14 Gen2 (e1000e) Status in OEM Priority Project: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: I recently got a Thinkpad T14 Gen2 with a I219-V network adapter (8086:15fc). I get very slow connection speeds and even total loss of connectivity without seeing much in the logs (like dmesg etc.). ethtool reports CRC errors and paket loss. Besides Ubuntu 21.04/kernel 5.11 I tried to install Ubuntu 20.04 (kernel seems to old) and i tried the e1000e driver directly from upstream (3.8.7) with no success. A strange behaviour I observed: if connectivity is lost (notebook is not reachable via ping from another host), if I do something like "ping 8.8.8.8" on the notebook itself, it becomes reachable from the other host again. Downloads in general are very slow if they work at all. WLAN (AX210) seems to work fine, wired network using a USB-network adapter works fine, too. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu65 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ros 3285 F.... pulseaudio CasperMD5CheckResult: pass DistroRelease: Ubuntu 21.04 HibernationDevice: RESUME=none InstallationDate: Installed on 2021-05-07 (2 days ago) InstallationMedia: Ubuntu 21.04 "Hirsute Hippo" - Release amd64 (20210420) MachineType: LENOVO 20W0004MGE NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair Package: linux (not installed) ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/BOOT/ubuntu_n51dtp@/vmlinuz-5.11.0-16-generic root=ZFS=rpool/ROOT/ubuntu_n51dtp ro quiet splash vt.handoff=1 ProcVersionSignature: Ubuntu 5.11.0-16.17-generic 5.11.12 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
