Bug ID: 38953
           Summary: Linux kernel version 4.2 will prevent Battle.net App
                    from launching in Wine
           Product: Wine
           Version: 1.7.47
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

When using Linux kernel version 4.2 (all of the release candidates exhibit this
phenomenon), the Battle.net will fail to launch in Wine (1.7.47). When
switching back to the stable 4.1.2, it will resume functioning as expected.

Obviously, this hints at an issue somewhere in the Linux kernel but,
ultimately, there is no way to bug report on kernel.org when the problem is one
individual application.

There have been some (very) low level changes in the Linux kernel between 4.1
and 4.2 and consequently, it may have affected Wine in some fashion. I suspect
something related to the low level ASM changes (see changelogs for the 4.2
rc's).

This was tested with all currently available release candidates for Linux
kernel version 4.2 (rc1, rc2, rc3).

Hardware: AMD A6-3650
Kernel versions: 4.1.2 amd64 low latency (works); 4.2rc1/rc2/rc3 amd64 low
latency (does not work)
Wine: 1.7.47
Graphics stack: Mesa 10.7 (git, oibaf).
