Comment 4 for bug 1859756

@Fred: In comment #3 you state "this patchset have cause some error". If this patch set has introduced a bug, please report that in a new bug. However, since you moved the Ubuntu-18.04 task back to "New" at that time, I wonder if your intent was to demonstrate that those patches are *required to fix* a bug in 4.15.

  1) Can you clarify the above?

  2) Which kernel version created the log in Comment #3?
