I'll try to bring my own contribution, as I searched for 2 hours. I think I just figured out how to solve the problem, I just got it. But my solution is a bit more simple I guess:cd /usr/share/arduino/lib
sudo cp librxtxSerial* ../
For me swap is useful: I have 3gb ram and 2gb swap (OCZ SSD),I can still use the system with a bit of lag with the swap almost full (fiefox opera with a lot of tabs,amule,thunderbird,amsn etc... with many days of uptime). HD swap would be deadly slow instead.
In case anyone is wandering, the correct incantation is 'systemctl hibernate'.https://wiki.archlinux.org/index.php/Sy … managementPSA: Searching the wiki for 'hibernate' points to https://wiki.archlinux.org/index.php/Pm-utils , which reportedly needs some updating wrt systemd.I know nothing about hibernating, so if someone could help, please contribute.
This issue may be related to Syslinux 6.02, which has been identified and fix in the latest ISO. See https://bbs.archlinux.org/viewtopic.php?id=173665 and https://bbs.archlinux.org/viewtopic.php?id=172588 for further information.
zramswap and zswap are two different animals.I had some issues with the former: https://bugs.archlinux.org/task/36574 but I've been using zswap for over a week now and everything's fine.Getting more RAM or using less RAM - .e.g not opening 20 tabs with multimedia content at once - will surely remedy the situation too.
