------- Comment From geraldsc@de.ibm.com 2021-01-19 09:51 EDT------- BTW, you seem to have a really good testcase for THP, at least you are able to trigger all kind of THP issues (at least on s390 :-)). What exactly is your system setup? Is it a KVM or z/VM guest, or did it maybe crash in a KVM host or LPAR? The workload you are using is some "SUSE build sevice", right?
