Bug#866122: slapd-mtread crash on ppc64{,el} in stretch/sid

[Barry Arndt]

A few things:
 
I verified that this problem does not recreate on buster, as Ryan 
mentioned earlier, because of the disabling of lock elision in glibc.
 
I verified that this problem still exists on a Debian 9.8 base with 
upstream kernel 5.1.0-x, which contains up-to-date TM fixes.
 
Our kernel team is actively debugging this problem on upstream kernel 
5.2.0-rc5, and is in favor of disabling TM in Debian until this issue is 
resolved.
 
Thanks.
