Public bug reported:
1. Run a rebooter script on Turin blade with AMD GPU MI210 installed in
Gdale
Result: After 300+ reboots OS (Ubuntu) hangs (see image attached)
Rebooting OS will fix an issue.
Seen on multiple blade setups. No hangs observer with less than 300
loops so far.
Here is a Linux grub workaround provided by AMD (also see image
attached):
Please disable 5-level page tables. Here is how to do it:
1. Open the GRUB configuration file: sudo nano /etc/default/grub
2. Add no5lvl to the list of parameters: GRUB_CMDLINE_LINUX="... no5lvl"
3. Add add iommu=pt to GRUB_CMDLINE_LINUX_DEFAULT
4. Update GRUB: sudo update-grub
5. Reboot the system.
