[Kernel-packages] [Bug 1832101] Re: systemd-networkd: Lost carrier e1000
I'm having this issue as well, with the 5.0.0-16-generic kernel on amd64 and an Intel I219-V NIC using the e1000e driver. I have a test case that can reproduce it somewhat reliably (involving a lot of concurrent back- and-forth chatter on my LAN). I was able to reproduce it even after this command: ethtool -K enp0s31f6 gso off gro off tso off rx off tx off although anecdotally, disabling those features makes reproduction harder. After the original oops with backtrace (similar to the one posted above), the problem presents simply as: Jun 14 03:54:43 good-fortune systemd-networkd[7815]: enp0s31f6: Lost carrier Jun 14 03:54:43 good-fortune systemd-networkd[7815]: enp0s31f6: DHCP lease lost with no further backtraces. -- 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/1832101 Title: systemd-networkd: Lost carrier e1000 Status in linux package in Ubuntu: Confirmed Bug description: Just installed a fresh installation of ubuntu 19 on our server and we're having a lot of carrier-lost erros. There is no really good indicaton why this is hapening. Tried the following : disabled ipv6 (just to be sure), on nic set GSO,GRO,TSO to off. removed netplan, switched to systemd-networkd and added configurewithoutcarrier to true, the option ignorecarrierlost is not accepted by systemd.

[Kernel-packages] [Bug 1815508] Re: Xorg freezes due to kernel hung task in the i915 driver
I use ZFS. I looked here: https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.20.11/ and it looks like linux- modules-4.20.11-042011-generic_4.20.11-042011.201902200535_amd64.deb does not provide a zfs.ko. Given that the bug may take days to reproduce, is there a way I can perform this testing without losing access to my ZFS filesystem?

[Kernel-packages] [Bug 1815508] Re: Xorg freezes due to kernel hung task in the i915 driver
Following advice I saw on Stackexchange, I've been setting `intel_iommu=igfx_off` on the kernel command line; this seems to mitigate, but the bug still occurs. I've submitted a redacted version of the apport-collect output, which I hope is enough. I will tentatively mark the bug confirmed. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- 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/1815508 Title: Xorg freezes due to kernel hung task in the i915 driver Status in linux package in Ubuntu: Confirmed Bug description: This bug is present in 18.04 and is triggered by specific actions, in particular, paging through image galleries in Eye of Gnome.

[Kernel-packages] [Bug 1815508] [NEW] Xorg freezes due to kernel hung task in the i915 driver
Public bug reported: This bug is present in 18.04 and is triggered by specific actions, in particular, paging through image galleries in Eye of Gnome. When the bug is triggered, Xorg freezes completely and goes into the D (uninterruptible sleep) state. The machine continues to respond to ping and ssh. When triggering a shutdown or reboot over ssh, the shutdown process continues normally until most userspace processes (including systemd-journald) have been stopped, but then hangs. The system can still be rebooted with the magic sysrq technique.
