After upgrading HWE-16.04-kernel from 4.15.0-48 to 4.15.0-50 the kernel crashes while booting as PVH-Guest with Xen 4.12. Kernel 4.15.0-48 and prior did boot without any problems.
We have the same problem for Ubuntu 18.04 with Kernel 4.15.0-50. Ubunutu 18.04 with HWE-Kernel 4.18.0-20 boots without problems as PVH-DomU.

=== SRU Justification ===
[Impact]
NULL pointer dereference in acpi_quirk_matches_bios_ids() renders kernel
unbootable.
[Fix]
It's a regression caused by commit abd273f52766 ("UBUNTU: SAUCE: ACPI /
bus: Add some Lenovo laptops in list of acpi table term list").
When both bios_vendor and bios_ver are NULL then a NULL string is passed
to strncmp() and the issue occurs.
VMs may not provides string bios_vendor or bios_ver, so bail out early
when either bios_vendor or bios_ver is NULL.
[Test]
User reported the test kernel with proposed fix solves the issue.
[Regression Potenial]
Low. It's quite trivial so I don't think it'll regress anything.
