memcpy: detected field-spanning write (size 20) of single field "xattrstart"

[Andreas Hasenack]

I created a zfs-encrypted pool at /dev/sda (a 16Gb pendrive), to use it as storage for lxd on this raspberry pi5 with 8Gb of RAM.

Creating the pool worked just fine, as did making it a storage for lxd. I then launched a test container, and it hung.

Hi Andreas,
we have an initial version of the plucky raspi kernel available in our bootstrap ppa (6.14.0-1003.3). Could you maybe check if it resolves the problem? The kernel that currently comes with plucky is an old oracular kernel. https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/bootstrap

[Andreas Hasenack (ahasenack)]

This kernel seems better so far, no backtraces yet, thanks! Hope it can make it into plucky still!
