해결방법
Using: echo 1 > /sys/bus/pci/devices/0000\:09\:00.0/remove echo 1 > /sys/bus/pci/rescan
You can create a .sh chmod +x and add it to cron
File: /root/fix_gpu_pass.sh
Note Change “0000\:0X\:00.0” for your GPU PCI ID
#!/bin/bash echo 1 > /sys/bus/pci/devices/0000\:0X\:00.0/remove echo 1 > /sys/bus/pci/rescan
Add to cron:
crontab -e
add:
@reboot /root/fix_gpu_pass.sh
