[Bug 1495983] Re: [Hyper-V] kernel panic occurs when installing Ubuntu Server x32

 

It does not look like the patch "storvsc: use small sg_tablesize on x86"
ever landed in mainline.  That is the reason Xenial does not have it.

It doesn't appear there was any more discussion upstream after 2 Oct 2015:
https://lkml.org/lkml/2015/10/2/550

Do you know the status of getting this patch upstream?

If needed, I can submit a SAUCE patch for 16.04 like we did for prior
releases.

  I tried with the builds from 14th and 15th of September with the same result. This bug does not affect x64 builds.
  Tried to start the installation with different resources with no effect, kernel panic always occurs no matter the VM settings.
