Bug Description

When trying to commission an arm64 machine with 2.8.0~beta4 (8502-g.942cfc7e9), it gets into Failed Commissioning and 50-maas-01-commissioning is marked as failed.

The output of 50-maas-01-commissioning is:

  ERROR: Failed to retrieve CPU information: Failed to get CPU cache information: Failed to read "/sys/devices/system/cpu/cpu0/cache/index0/size": open /sys/devices/system/cpu/cpu0/cache/index0/size: no such file or directory

Can we get a `find /sys/devices/system/cpu/cpu0/` please?

LXD skips caches if the cache directory or the level file are missing, sounds like in this case you have a directory, cache level by no size? not sure why the kernel would expose it that way...

Note that none of cpu entries have a "size" file:

ubuntu@arm64:~$ ls -l /sys/devices/system/cpu/cpu*/cache/index*/size
ls: cannot access '/sys/devices/system/cpu/cpu*/cache/index*/size': No such file or directory
