Call Trace:

This issue also happens when deleting k8s pod if VF is used by k8s pod, there was a bug reported in the e1000-devel mailing list

The fix is suggested by Billy McFall, to add protection when accessing the hash list(vsi->mac_filter_hash), but it's not upstream yet

[Test Case]
Spin up some VMs with VFs, then delete all VMs

[Regression Potential]
Low, the fix is to add a protection for a hash list, shouldn't have potential regression

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-eoan' to 'verification-done-eoan'. If the problem still exists, change the tag 'verification-needed-eoan' to 'verification-failed-eoan'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

The general protection fault is reproducible with the current 5.3 kernel as follows by creating 10 SR-IOV enabled VMs with OpenStack and deleting 5 VMs sequentially. After updating it to the -proposed one as
 linux-image-5.3.0-25-generic 5.3.0-25.27, there is no such general protection fault happened with the same operations. So we can consider the fix is verified.
