Hi Felix, Well on Ubuntu the config used for each installed kernel is found in /boot e.g. /boot/config-`uname -r` But that name or location might be different on other systems. You should grep for VM86, e.g. grep VM86 /boot/config-`uname -r` Depending on which kernel version you are checking the response may be different e.g. on my 3.19 system I get ajb@polly:~$ grep VM86 /boot/config-`uname -r` CONFIG_VM86=y I expect a 4.2 32bit system to have a variable called X86_LEGACY_VM86 if it's set to 'n' then the syscall is not enabled on that system. If it's important to you then please report it as a regression in the distro's bugtracker.
