Bug ID: 36707
           Summary: wineboot hangs (loops?) with 100% CPU
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]

Might be Wine bug #36664 
Looks like RedHat bug #1097970

Wine 1.6.1 worked very well in Ubuntu 12.04, for years, until the patch below
was applied.

( from: /var/log/apt )

Start-Date: 2014-06-07  06:10:33
Commandline: aptdaemon role='role-commit-packages' sender=':1.323'
Install: linux-headers-3.2.0-64:amd64 (3.2.0-64.97),
linux-image-3.2.0-64-generic:amd64 (3.2.0-64.97),
linux-headers-3.2.0-64-generic:amd64 (3.2.0-64.97)
Upgrade: linux-generic:amd64 (3.2.0.63.75, 3.2.0.64.76),
linux-headers-generic:amd64 (3.2.0.63.75, 3.2.0.64.76),
linux-image-generic:amd64 (3.2.0.63.75, 3.2.0.64.76), linux-libc-dev:amd64
(3.2.0-63.95, 3.2.0-64.97)
End-Date: 2014-06-07  06:13:55

After that patch Wine locks/hangs in wineboot with 100% CPU (one core) use.
I tried running Configure Wine to eliminate potential application dependencies
and see the same behavior starting it. 
When I kill the wineboot process wincnfg starts and takes 100% of CPU until
killed.
Same situation with Wine 1.7.18 in Ubuntu 12.04
Same situation with Wine 1.6.2 in Ubuntu 14.04

Things I've tried that did NOT fix or change the problem:

Reinstall Wine 1.6.1  ( wine1.6:amd64 (1.6.1-0ubuntu1~ppa1~precise1) )
Instal Wine 1.7.18 
Remove Wine 1.7 and (re)install 1.6.1
Replace open source video driver with Nvidia proprietary driver.
Upgrade to Ubuntu 14.04 and Wine 1.6.2

Hello tebclause,

yes, the symptoms you describe are exactly bug 36664

Next time please _comment_ on the bug since you already suspected the correct
one (bug 36664) instead of creating a dupe.

See here:
http://cloud-images.ubuntu.com/releases/12.04.2/release/unpacked/release_not...

The Linux kernel was updated from 3.2.0.63.75 [3] to 3.2.0.64.76 [4]
...
  * x86-64, modify_ldt: Ban 16-bit segments on 64-bit kernels
    - LP: #1319885
--- quote ---

Wine was deliberately broken to fix a potential security issue.

"a few 16-bit apps" ... sure.
A lot of 32-bit installers still carry 16-bit (legacy) parts.

Same breakage happened with Fedora distro I use.

There is a temp patch, making it a runtime option:

https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/commit/?id=fa81511b...

and some work to fix it properly: https://lkml.org/lkml/2014/5/4/376

It might take some time until distros backport this too.
Until then you are stuck with booting older kernels.

Regards
