Since considerable time I'm doing kernel builds (make -j8) on an openSUSE Tumbleweed system on top of dm-crypt and an NVMe SSD but I have not yet encountered any kind of lockup. Maybe another driver, e.g. an I/O scheduler, is responsible for the lockups? Bart. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
