[Description]
[Test Case]
[Where things could go wrong]
[Other] |
[Description]
On a VM on Azure with a Tesla gpu it was noticed that when removing the gpu from the pci the vm would crash. In case the nvidia drivers are loaded, the machine won't crash. Instead the removing process will hang and the machine will crash on reboot.
This is related to bug [1].
The bug reported in [1] regards another driver but the root cause is the same.
It is still investigated whether this is a bug in pci, or it is a bug of various drivers on how they use pci.
For this case we have identified that removing commit [2] prevents the kernel crashes.
Azure has requested to revert this commit, at least for the time being.
This commit is not in upstream, so it just need to be reverted from Ubuntu kernels.
[Test Case]
On an Azure vm with a gpu :
# echo '1' > /sys/bus/pci/devices/0001:00:00.0/remove
where '0001:00:00.0' the pci address of the gpu.
The vm will crash.

The commit to be reverted was included in a patchset to address lp bugs https://bugs.launchpad.net/bugs/2023071 and https://bugs.launchpad.net/bugs/2023594
However this commit just reduces boot time and removing shall not introduce any regressions.
Side effects will be increase in the boot time.
[Other]
Only Ubuntu azure kernels are affected :
- Jammy 5.15
- Lunar 6.2
Focal is also affected since it's using 5.15 kernel.
This commit does not appear in Mantic 6.5 kernel.
