[PATCH] server: Accept DBG_EXCEPTION_HANDLED parameter in continue_debug_event.

[Francois Gouget]

I figured it out... I think.

This issue happened before:
https://bugs.winehq.org/show_bug.cgi?id=40240
https://bugs.launchpad.net/qemu/+bug/1658141

The Windows crash message was a bit different but the host had similar 
MSR_* errors on the console.

The workaround then was to run:

  echo 1 >/sys/module/kvm/parameters/ignore_msrs

But I set up an init.d script to get it to survive across reboots and 
unfortunately that script's dependencies were incorrect so, at least 
recently, it got run before /sys was mounted. But not always. This 
explains the sometimes puzzling and somewhat inconsistent results I got.
It also explains why a simple reboot on the 27th broke ntdll:exception.

Had I noticed the "/kvm/.../parameters/" part of that path I may have 
realized that the right way to make this workaround permanent, at least 
on Debian, is to do:

  echo options kvm ignore_msrs=1 >/etc/modprobe.d/local-qemu.conf

But, unlike before, that's not entirely sufficient: it does not work 
with QEmu 3.1; one has to upgrade QEmu to 5.0-14. I have done that on 
vm3 and vm4, restored the kernel to the latest 4.19.0-13 (it works with 
5.9.0 too), and I have rerun WineTest on w864, w1064* and w10pro64.
