My system has been crashing regularly without helpful log data on recent kernels. The sequence of events is thus:ClixTrix wrote: ⤴Mon May 07, 2018 7:32 am Since my last post to you, there is a BIOS fix issued by AMD for the Ryzen idle freeze problem. Since you've updated to a 2700x, you probably updated the BIOS to current release. Look in BIOS settings for "PSU Idle Control" and set it to "Typical Current Idle". It probably is in the same section of BIOS where the C6/Global C-States settings are found.
1: While running a 4.8 series kernel I replaced my motherboard, memory and CPU.
2: Linux Mint began using 4.10 series kernels.
3: I updated to the 4.10 series kernels
4: I began experiencing regular hard crashes which left behind no consistent information in syslog other than series of null bytes which sequentially grew longer if I didn't restart.
5: I downgraded to 4.8 series kernels for several months because I needed a stable system.
I unsuccessfully attempted to troubleshoot the problem before downgrading by:
A: Using 4.11, 4.12 and 4.13 series kernels.
B: Flashing my motherboard BIOS to the most recent version.
C: Not using bluetooth. (The system continued to crash, though significantly less frequently.)
D: Running memtest (clean)
E: Reinstalling Nvidia proprietary drivers, though the problems began before I also replaced my graphics card.
F: Extensive googling for similar issues.
Some months later, I've reinstalled my entire system because I was aware that this bug likely awaited me if I updated to mint 18.3 and I wanted to be able to use more recent kernels. Despite a completely fresh installation running 4.10.0-42-generic, I began to again experience crashes.
Because the crashes persist through a clean system install, I can only assume that the problem is a hardware one.
EDIT: I can confirm that Ubuntu-based distros all suffer the same problem, I just had a live session of Ubuntu GNOME running from a USB drive crash with the same symptoms on my machine.
