There is no apparent logic in the pattern with wich the system hangs and I cannot provide any steps to reproduce the problem. One time it happened as I clicked a link in Firefox, new tab opened and the system froze. Another time, Firefox was not open and I was about to edit a text file by clicking "F4 Edit" in Krusader and the system froze. When the system freezes, it is completely unresponsive and there are no other options than to reset and reboot. The system generates no error reports as far as I can figure out and the only apparent info are some entries in the syslog. I have appended relevant info below, if further info may be needed please ask :) [b]inxi -Fz[/b] System: Host: computername Kernel: 4.19.1-041901-generic x86_64 bits: 64 Desktop: KDE Plasma 5.12.6 Distro: Ubuntu 18.04.1 LTS Machine: Device: desktop Mobo: ASUSTeK model: PRIME A320M-A v: Rev X.0x serial: N/A UEFI: American Megatrends v: 4023 date: 08/20/2018 Battery hidpp__0: charge: 80% condition: NA/NA Wh CPU: Quad core AMD Ryzen 5 2400G with Radeon Vega Graphics (-MT-MCP-) cache: 2048 KB clock speeds: max: 3600 MHz 1: 1454 MHz 2: 1418 MHz 3: 1419 MHz 4: 1419 MHz 5: 1419 MHz 6: 1419 MHz 7: 1436 MHz 8: 1582 MHz Graphics: Card: Advanced Micro Devices [AMD/ATI] Vega [Radeon Vega 8 Mobile] Display Server: x11 (X.Org 1.19.6 ) drivers: ati,amdgpu (unloaded: modesetting,fbdev,vesa,radeon) Resolution: 1680x1050@59.88hz OpenGL: renderer: AMD RAVEN (DRM 3.27.0 / 4.19.1-041901-generic, LLVM 6.0.0) version: 4.5 Mesa 18.0.5 Audio: Card-1 Advanced Micro Devices [AMD] Device 15e3 driver: snd_hda_intel Card-2 Advanced Micro Devices [AMD/ATI] Device 15de driver: snd_hda_intel Sound: Advanced Linux Sound Architecture v: k4.19.1-041901-generic Network: Card: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller driver: r8169 IF: enp5s0 state: up speed: 100 Mbps duplex: full mac: <filter> Drives: HDD Total Size: 250.1GB (26.2% used) ID-1: /dev/nvme0n1 model: Samsung_SSD_970_EVO_250GB size: 250.1GB Partition: ID-1: / size: 228G used: 61G (29%) fs: ext4 dev: /dev/nvme0n1p2 RAID: No RAID devices: /proc/mdstat, md_mod kernel module present Sensors: System Temperatures: cpu: N/A mobo: N/A gpu: 26.0 Fan Speeds (in rpm): cpu: 0 Info: Processes: 232 Uptime: 22 min Memory: 1176.8/6960.8MB Client: Shell (bash) inxi: 2.3.56 [b]SYSLOG[/b] Prior to the first relevant entry posted here is a CRON entry @ 13:18:01 which seems unrelated to the issue.
