[Kernel-packages] [Bug 1785856] Re: hung task flush-zfs
The mainline kernel builds do not seem to have the zfs kernel modules. I have lxd configured to use a zfs pool. Where can I get the zfs kernel modules compiled against the mainline kernel? -- 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/1785856 Title: hung task flush-zfs Status in linux package in Ubuntu: Incomplete Bug description: After restoring a snapshot on a running container a hung task task oops trace gets logged for flush-zfs.

[Kernel-packages] [Bug 1785856] Re: hung task flush-zfs
Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.18 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
