Hello everyone: I have installed OpenSuse Tumbleweed. Normally i use dosemu for a program dos writen. I perform the updates from time in time ( 3~4 months) In the last week i upgrades the system and DOSemu stop working. my_pc> dosemu LOWRAM mmap: Invalid Argument I search on internet and all problems are very old of years 2012, 2014 and i was working until december of 2019. I try the following: 1) from: https://www.spinics.net/lists/linux-msdos/msg01250.html (2010) Disable 'apparmor' completely. Use the kernel boot option 'apparmor=0' to achieve that. (add it to /boot/grub/menu.lst). 2)from https://sourceforge.net/p/dosemu/bugs/398/ (2012) sysctl -w vm.mmap_min_addr=0 The warning disapear, but the dosemu never start and i cant find a log o clue about what is happening. The file .dosemu/boot.log is updates without errors only a warning about vm86 not present. 3) run dosemu as root. the same as 2) but sysctl is not required. I am completely loosed, any clue will be welcome Best Regards Christian echo 0 > /proc/sys/vm/mmap_min_addr -- Be Free, Be Linux -- To unsubscribe, e-mail: opensuse-support+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-support+owner@opensuse.org
