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- disco' to 'verification-done-disco'. If the problem still exists, change the tag 'verification-needed-disco' to 'verification-failed-disco'. 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.

Given panic stack trace (see attachment), I've narrowed down the bug to ixgbe_ipsec_vf_clear function in upstream ixgbe driver: https://github.com/torvalds/linux/blob/72cf0b07418a9c8349aa9137194b1ccba6e54a9d/drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.c#L840 When I comment its usage (https://github.com/torvalds/linux/blob/72cf0b07418a9c8349aa9137194b1ccba6e54a9d/drivers/net/ethernet/intel/ixgbe/ixgbe_sriov.c#L734), everything works as expected (I'm not using any ipsec feature). Didn't try to fix the ixgbe_ipsec_vf_clear function though. Please find attached a stack trace collected using IPMI serial-over- lan.

[Kernel-packages] [Bug 1829652] Re: Kernel panic upon resetting ixgbe SR-IOV VFIO virtual function using 5.0 kernel

Could reproduce with 5.0.0-13-generic and 5.0.0-15-generic, doesn't happen with 4.18.0-20-generic. I'm using libvirt and VM is using KVM, XML snippet to delegate virtual function to VM is: As soon as I start the VM using "virsh start vm", kernel panics. I'm using X550T intel NIC (lspci output: Ethernet controller: Intel Corporation Ethernet Controller 10G X550T (rev 01)) on a Supermicro X11SSH-CTF motherboard, with up to date bios and 4 virtual functions (class/net/em1/device/sriov_numvfs = 4). Given panic stack trace (see attachment), I've narrowed down the bug to ixgbe_ipsec_vf_clear function in upstream ixgbe driver: https://github.com/torvalds/linux/blob/72cf0b07418a9c8349aa9137194b1ccba6e54a9d/drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.c#L840 When I comment its usage (https://github.com/torvalds/linux/blob/72cf0b07418a9c8349aa9137194b1ccba6e54a9d/drivers/net/ethernet/intel/ixgbe/ixgbe_sriov.c#L734), everything works as expected (I'm not using any ipsec feature).
