Bug Description

SRU Justification

[Impact]

Microsoft relayed a customer report of failures when trying to take a kdump.

These 3 patches fix the issue:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/video/fbdev/hyperv_fb.c?id=aa5b7d11c7cb87c266d705b237368985e7171958
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/hv/channel_mgmt.c?id=77db0ec8b7764cb9b09b78066ebfd47b2c0c1909
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/hv/channel_mgmt.c?id=8c2d5e0640e53c14b6240e9bf1e32a2226e6e6ca

Patch #1 solves a problem where the “Unable to send packet via vmbus” message is output continuously. But with that problem fixed, the second problem can occur where the kdump kernel panics due to receiving an unexpected VMbus UNLOAD complete message.

Patch #2 prevents the UNLOAD complete message from ever occurring in the kdump kernel. But if the UNLOAD complete message does occur at some unexpected time, Patch #3 prevents it from causing a panic.

These patches seem worthy of application to all affected master kernels.

[Test Plan]

Cause a guest kernel to crash and successfully acquire a kdump.

[Where problems could occur]

The extended Hyper-V wait while flushing could cause side effects.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1927518

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Since these packets were by request of Microsoft I'm going to call this verification-done. Test kernels have been available, though no test results have been reported. Its likely safe enough since these commits affect only Azure kernels.

That last part about these patches only affecting Azure kernels is not correct. These patches were actually applied to all of the master kernels. However, chance for regression is pretty small since they only have an impact when a VM is shutting down.
