FWIW, I decided to do some testing on my more "powerful" desktop. Not a fan of suspending it in the past due to video issues....long story. Anyway, my desktop is running [egreshko@meimei ~]$ uname -r 4.17.5-200.fc28.x86_64 I then started an F28 VM under QEMU. For sort of proper support of IPv6 I use a mactap and my links are as follows.... egreshko@meimei ~]$ ip link show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000 link/ether 40:61:86:7c:2b:db brd ff:ff:ff:ff:ff:ff 3: wlp4s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DORMANT group default qlen 1000 link/ether e6:87:9b:80:eb:8b brd ff:ff:ff:ff:ff:ff 4: wlp0s29u1u2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000 link/ether cc:e1:d5:3e:88:e7 brd ff:ff:ff:ff:ff:ff 5: macvtap0@enp2s0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 500 link/ether 52:54:00:e9:37:ee brd ff:ff:ff:ff:ff:ff I then suspended the desktop using "echo mem > /sys/power/state" The power button on the desktop almost immediately glowed amber and the monitor showed "blue" indicating it had no input. I pushed the power button to restore and everything came up well. (Aside from some video issues). I then did this 6 more times with no problems. Again, there were only 3 or 4 lines in the journal when I issued the "echo" command. The journal then seemed to pick up with suspend info *after* I hit the power button. So, I would recommend you try the "alternate" method to suspend your system to see if it helps in any way. -- Conjecture is just a conclusion based on incomplete information. It isn't a fact.
