Neither here nor there you said what the baseline is (i.e. what the last kernel was that didn't have that regression).

Can you apply this patches to kernel-xen?

Patches get applied to all kernels, or none of them. Furthermore, in the mail above you (validly) ask whether you problem might be related to those patches - did you meanwhile gain any knowledge that they in fact are? If not, are you expecting us to apply patches "just in case"?

1) https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=... aaf6d3d3d1e95f4be07e32dd84aa1c93855fbbd

To me this doesn't look like something suitable for backporting, but our networking people would need to decide this anyway.

2) https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=... ecd1a75d977e2e8c48139c7d3efed183f898d94

The equivalent of this applicable to our kernel already is in our master branch.

3) https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=... 810e5b9a7731ca5fce22bfbe12c96e16ac44b6f

This patches code that doesn't get built in our kernel. Furthermore this is a backend patch, but the crash you reported is in the frontend. Nevertheless the plan is to have similar code in our kernel, I just didn't get around to do the porting work yet.

4) https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=... 3393fd5cc2b6cdeec32b704ecba64dbb0feae3c

The equivalent of this applicable to our kernel again already is in our master branch.

I'm going to avoid that mistake in the first place when porting the patch listed as 3) above. All in all, from what I can tell so far, patches 2-5 are unrelated to your problem.

Just wanted to let you know that our master branch now has these
changes. Nevertheless (as said later in this thread) I don't think the
lack thereof is responsible for the frontend crashes you observe,
but you're welcome to give those changes a try.
