There are _numerous_ similar bugs reported in the last 10+ years, in redhat's bugzilla, ubuntu, suse and others.
Almost all of them get closed because they get old and no-one is willing to do the necessary work to refine the bug report to dependable reproducibility.
And that's not surprising really; it's hard, time-consuming work which may be obsoleted on the next kernel version.
That said, some have written memory stressors and have been able to crash or stall a machine but it's still a bit hit and miss.
