Errors at launch - Mouse and Keyboard interrupted

Hi,

Freshly installed LEAP 42.2 on my computer, at reboot, my system say:

The system boot slowly…
At graphical interface (gnome) the mouse intermittently interrupted and system blocking during interrupt, the keyboard is very very slow.

All updates have been applied / Reboot / same problem

No problem during installation

Not tested with LEAP 42.1 (new motherboard)

My system:

MSI 970FX Gaming (UEFI)
AMD Athlon 64 FX x4 @4.25Ghz
16Gb of RAM
2 x AMD Radeon R7
Silicon image IDE RAID controller
