[Kernel-packages] [Bug 1756337] Re: kernel bug at fscache/operation.c

2018-03-16 Thread Andres Rodriguez
Hi There,

The MAAS images use the kernels that are available in the archive. Since
this is a kernel issue, I'm retargetting to the linux package in Ubuntu.

If this is already fixed, MAAS will automatically update new images once
the packages are available in the archive, otherwise, please feel free
to use a different kernel (e.g. hwe-16.04) and see if that fixes your
issue. Just make sure your images are latest.

** Changed in: maas
   Status: New => Invalid

** Also affects: linux (Ubuntu)
   Importance: Undecided
   Status: New
