Some SSD drives made by LiteOn can crash the kernel due to bad drivers. A fix for this issue has been submitted upstream: https://git.kernel.org/pub/scm/linux/kernel/git/tj/libata.git/commit/?h=for-4.15-fixes

LITEON EP1 has the same timeout issues as CX1 series devices.

Revert max_sectors to the value of 1024.

At a high level the root cause of this problem is that the device only supports commands with a transfer size up to 512KB. This worked fine with older versions of Linux but newer versions are attempting commands with a transfer size of 1280KB which is problematic for this device (LITEON EP1-KB480)
