Description of problem:
Since I have updated to kernel 3.14.3, I can no longer start Ms Access 2000 under wine. When I run wine it prints:
modify_ldt: invalid argument
a couple of times on the command line but Ms Access doesn't open. In the background the wineboot.exe process takes 100% of cpu.

Version-Release number of selected component (if applicable):
kernel-3.14.3-200.fc20.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Install the above kernel and wine
2. Try to run Ms Access under Wine (probably any 16-bit program will do)

Actual results:
Wineboot.exe keeps running at 100% cpu
The following error is printed a couple of times on the console
modify_ldt: invalid argument

Expected results:
Normal start of the wine application.

Additional info:
A quick search on the internet led me to this discussion on lkml:
https://lkml.org/lkml/2014/4/11/529

It seems to talk about this issue so may be relevant to this bug.

Also when I revert to kernel 3.13.10 (the previous kernel I was using) everything works fine.

Thanks.  I forwarded this on to the upstream discussion.

FYI, identical issue with Wine & MS Money 2004 :
- works up to and including kernel 3.14.2, 
- "modify_ldt: invalid argument" & lock-up with kernel 3.14.4.

> FYI, identical issue with Wine & MS Money 2004 :

Linus' patch (https://lkml.org/lkml/2014/5/7/508) is included in 3.14.7-200.fc20.x86_64 :

# echo 1 > /proc/sys/abi/ldt16

allows MS Money to start without Wine hogging the CPU at 100%.

Comment 4 Josh Boyer 2014-06-20 12:58:53 UTC

Indeed.  Thanks for pointing that out.  That solution is about is good of a fix as we'll get.
