Need help fixing Xorg and kernel crash
BIOS
Micro-Star International Co., Ltd MS-7C02/B450 TOMAHAWK MAX II
You have an old BIOS version H.30 from 11/30/2020. A newer BIOS, H.50 from 05/13/2021, is available at https://www.msi.com/Motherboard/support/B450-TOMAHAWK-MAX-II#down-bios.
Memory/Swap
You may have more than one problem here. The miner application is getting killed by OOM (out of memory) process. The /swapfile should be enough for 32G of RAM, but maybe not. We'll try and increase the /swapfile from 2G to 4G and see if that helps.
Note: Incorrect use of the rm and dd commands can cause data loss. Suggest copy/paste.
In the terminal...
sudo swapoff -a # turn off swap
sudo rm -i /swapfile # remove old /swapfile
sudo dd if=/dev/zero of=/swapfile bs=1M count=4096
sudo chmod 600 /swapfile # set proper file protections
sudo mkswap /swapfile # init /swapfile
sudo swapon /swapfile # turn on swap
free -h # confirm 32G RAM and 4G swap
Edit /etc/fstab, using sudo -H gedit /etc/fstab or sudo pico /etc/fstab.
Confirm this /swapfile line in /etc/fstab... and confirm no other “swap” lines... use SPACES in this line... confirm NO TABS...
/swapfile none swap sw 0 0
reboot # reboot and verify operation
Memtest
Note: AMD Ryzen processors are very fussy with memory compatibility.
Go to https://www.memtest86.com/ and download/run their free memtest to test your memory. Get at least one complete pass of all the 4/4 tests to confirm good memory. This may take a few hours to complete.
Update #1:
Miner
Note: Check to assure that you're running the latest version of miner.
I did not have the latest miner software. Checked for the latest release; and comments for the new version include: "fixed memory leaks on AMD GPUs", and "fixed compatibility with latest linux distributions". Going to install latest software version, hopefully does the trick.
Update #2:
After changing some overclock settings, and installing the newer version of the miner software, the computer has been running great.
