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

KASAN error is shown in the commit log: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v4.13-rc1&id=27463ad99f738ed93c7c8b3e2e5bc8c4853a2ff2 [Test Case] Unfortunately, KASAN arm64 support wasn't mature enough to test with Ubuntu kernels (< 4.13), so we can't test this directly on an Ubuntu tree. Testing on Ubuntu is therefore limited to regression testing. [Regression Risk] The fix is localized to a driver that is specific to a HiSilicon SoC. Regression risk is mitigated by testing on that system (boot, generating network activity over a NIC that uses this driver).
