Dear Maintainer,

   * What led up to the situation?
After 57 days of uptime, I rebooted and picked up a new kernel (there were several kernel updates since early June). However, I was unable to start Notes7 under Wine. The result is that the program looped after generating these messages:
p11-kit: couldn't load module: /usr/lib/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so: /usr/lib/i386-linux-gnu/pkcs11/gnome-keyring-pkcs11.so: cannot open shared object file: No such file or directory 
modify_ldt: Invalid argument
modify_ldt: Invalid argument
modify_ldt: Invalid argument
modify_ldt: Invalid argument
modify_ldt: Invalid argument
err:module:find_forwarded_export module not found for forward 'krnl386.exe16.MapLS' used by L"c:\\windows\\system32\\KERNEL32.dll" 

I'm pretty sure the first of these is irrelevant.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   * What was the outcome of this action?
Web searching for terms in the final error message were unenlightening. Eventually, I was lead to a launchpad bug 1327532[1] and a Linux Kernel Mailing List discussion[2]. I was able to confirm that setting ldt16 to 1 resolved the problem and allowed Notes7 to start. 
    # echo 1 >  /proc/sys/abi/ldt16
From the linux-image-amd64 change log I saw that these two patches were included in the kernel on 29 Jun 2014 (linux (3.2.60-1) wheezy; urgency=medium"). I installed this kernel on July 7th. 

    - [amd64] modify_ldt: Ban 16-bit segments on 64-bit kernels
    - [amd64] modify_ldt: Make support for 16-bit segments a runtime option

Eventually, I found Wine bug 36664[3] and FAQ-10.22[4].
The diagnosis was made difficult because my error message was unusual in containing "find_forwarded_export" and my program is a 32-bit application. Apparently, even some 32-bit applications make use of 16-bit DLLs or functions.

This problem is very unlikely to get fixed in the 1.4 series.  For
anyone experiencing it, please use the workaround:

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

Best wishes,
Mike
