I've got a laptop that has started misbehaving on suspend.
About 1 in 10 suspends the laptop fails to fully suspend. It switches mostly off (screen off, etc.) but some of the motherboard keeps running. I know some of the motherboard keeps running because: - the wifi light remains on - the laptop will get hot because the fans don't start
The laptop does not respond to the power button to wake up. It's necessary to force halt & reboot the laptop by holding the power button down for a few seconds.
9 out of 10 times suspend works fine.
This appears to be a BIOS or kernel issue, since the last entries in the logs are:
May 29 09:02:17 sieve-deschouwer-co-za systemd[1]: Reached target Sleep. May 29 09:02:17 sieve-deschouwer-co-za systemd[1]: Starting Suspend... May 29 09:02:17 sieve-deschouwer-co-za systemd-sleep[21435]: Suspending system... May 29 09:02:17 sieve-deschouwer-co-za kernel: PM: suspend entry (deep) -- Reboot --
On a successful suspend I will additionally get:
May 29 08:21:32 sieve-deschouwer-co-za kernel: PM: Syncing filesystems ... done.
This started at the same time as I upgraded to F28. The laptop has previously worked fine since F24 or F25, or maybe earlier.
It's happened with a few different F28 kernel patchlevels.
product: HP ProBook 450 G2 (L8A81ES#ACQ) model name : Intel(R) Core(TM) i7-5500U CPU @ 2.40GHz 00:00.0 Host bridge: Intel Corporation Broadwell-U Host Bridge -OPI (rev 09) Linux sieve-deschouwer-co-za 4.16.11-300.fc28.x86_64 #1 SMP Tue May 22 18:29:09 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
Can anyone help me debug before I enter a bugzilla?

Do you still have a 4.14 kernel available? If you boot that does it work?

I didn't, but I did actually try and install F27 kernel. Seems to be Meltdown fixes related:
