 This is strange.
 
 Some time ago, I replaced the Core 2 Quad system of the original bug
 report by a HP DL360 G7 with dual Xeon L5630 CPUs, and the behavior of
 the rump/rumpkern/t_sp/stress_{long,short} test cases did not change:
 they still consistently failed with a timeout as reported.
 
 But recently, I noticed that they had started to consistently pass on
 the same hardware, and they passed even when I tested an old version
 of -current where they had previously failed.
 
 The only thing that has changed, that I can think of, is that I
 updated the system firmware from the version dated 2011-01-28 to
 2018-05-21, which includes fixes for various speculative execution
 vulnerabilities as well as other bug fixes.
 
 Has anyone else run the ATF tests on machine with 4 or more cores
 recently?  If so, did the rump/rumpkern/t_sp/stress_{long,short} test
 cases pass or fail?
