Hi, my computer runs manjaro kde for a couple years now and since a few days the entire system freezes shortly after booting up. i then tried to do a clean install from a live usb stick (up to date manjaro gnome) which had the same issue so i assume it has to do something with the kernel version, since that seems to be the cause for other people having similar problems. sadly i cant post any logfiles or anything because i only ever have about a minute until it freezes, giving me also no time to try any fixes like downgrading the kernel. im now posting this from a fedora live stick but dont really know how to proceed from here…
“Several days”? Any updates happend?
Would be helpful so see some informations about the hardware you’re using, because in case of freezes I can think of several bugs causing them (like the freeze-bug of early Ryzens) or the current amdgpu-firmware freezes of vega and navi.
Well, 1 minute isn’t much time, but did you try to get some informations via
# journalctl -b -1or
# dmesg?
It would also be possible to enter the grub-menu and alter the the commandline to
GRUB_CMDLINE_LINUX_DEFAULT="text"to prevent the xserver from starting and at least get some informations/logs without running into a possible gpu-related freeze.
So the fedora live usb is freezing too now, is this still a manjaro forum topic?At least i got this: I know text is preferred over pictures but its not possible for me to copy it that fast

I do upates for my machine every few days but im not sure if there were any major system or kernel updates right before the freezing started happening.
Right now, after removing the fedora usb i cant access my system at all, not even the bios, just all black so no chance of doing journalctl or any grub -menu things for me. am really not sure if this is a manjaro problem any more, but still in desperate need of help 
With (good 'ol) Sandy Bridge and also rather old Nvidia 970 it would be very unlikely any driver-optimizations causing this.
But more important:
it sounds like an ordinary hardware-failure. Time to replace components until it’s gone. Would start with GPU and then power supply unit.
i got the journalctl

demsg is incredibly long and i dont think i copied the whole of it, should i send it anyways?
