I tested it too in Trusty. Linux 3.13.0-32-generic from -proposed (used Synaptic to upgrade). Package linux-generic version 3.13.0.32.38.
I can now do "sudo sysctl abi.ldt16=1" to activate 16 bit support. Setting Windows 95 in winecfg now works correctly. Old 16 bit executables now start correctly (tried Elifoot 98 on an older version of 32 bit Wine using PlayOnLinux). Setting the option to 0 makes these issues return to the old behavior (as it should). It was a short test, so I don't know if there are regressions elsewhere or if the 16 bit executables still run exactly as before this problem. But this issue seems to be fixed @Ivan, to change the tags, look under the description of the bug, right above "Related branches", and click on the "pencil" (edit) button. But don't worry, I'll change it. ** Tags removed: verification-needed-trusty ** Tags added: verification-done-trusty -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1328965 Title: 3.13.0-29 kernel includes backport of 3.14 16-bit app restrictions but not override method causing wine win9x to fail Status in “linux” package in Ubuntu: Fix Released Status in “linux” source package in Trusty: Fix Committed Status in “linux” source package in Utopic: Fix Released Bug description: Kernel 3.13.0-29 evidently contains a backport of the 3.14 kernel security workaround that disables 16-bit binaries from running. This causes all wine Windows 95 and Windows 98 applications to fail. The 3.14 kernel also includes a feature to re-enable support for 16-bit binaries by providing the /proc/sys/abi/ldt16 interface. This part of the kernel patch was evidently not backported, so this ability to override the 16-bit application prohibition is not available. For this reason, I cannot move forward to new kernel releases until this is fixed.
