I built Xenial, Bionic and Cosmic test kernels with commit aec45e857c55. The test kernels can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1793086
Can you test this kernel and see if it resolves this bug? Note about installing test kernels: • If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages. • If the test kernel is 4.15(Bionic) or newer, you need to install the linux-modules, linux-modules-extra and linux-image-unsigned .deb packages.

Problem: qeth_query_oat_command() currently allocates the kernel buffer for the SIOC_QETH_QUERY_OAT ioctl with kzalloc. Solution: Using vzalloc() instead of kzalloc(), backing the allocation with non-contiguous memory. Commit -ID: aec45e857c5538664edb76a60dd452e3265f37d1 kernel 4.19. To be fixed for 18.10, 18,04 and 16.04.
