There is a bug: Kernel test lmbench bug/error which seems to be a recurring issue. It has been closed because it was opened as a kernel bug, and there doesn’t seem to be a category in bugzilla to reassign it. This needs to get visibility and resolved. Who is responsible for kernel test days? If this bug can’t be fixed then the documentation needs to be revised to remove the performance testing, or if kernel test days are no longer needed, they need to be discontinued.
In any event, we shouldn’t just ignore the situation.
