Hi everyone!
I’ve POS-machine with Gigabyte e350n motherboard. And it doesn’t start Xorg graphics after system loads. So I installed ATI video driver xf86-video-ati and now graphics work fine.
BUT after that I have another issue. Once 5-10 minutes my soft can’t reach RS232 (COM) port.
Give me some ideas to fix it, please!

Give us please some more details on how it was working before, which interface? (/dev/ttyS0, /dev/ttyUSB0 etc), which program are you using to connect and what is the exact error you get?
Please also post the output of “ls -l /dev/<device>”
Hi! I’ve found out what it was/
The problem was my touch driver used COM port but there wasn’t ISA IRQ settings turned on right in BIOS. 
Sorry for disturbing you.
