Created attachment 274989 [details] dmesg output my recently bought dell XPS 9370, running uptodate Debian Buster/Sid, sometimes wakeup by itself a short moment (like a second) after i've asked it to sleep, by pushing the power button for instance. looking through the kernel log i found these lines which made be suspicious of ACPI errors or devices refusing to sleep: [ 5210.962412] PM: suspend entry (s2idle) [ 5210.962413] PM: Syncing filesystems ... done.

my kernel is: Linux mkjlap 4.15.0-2-amd64 #1 SMP Debian 4.15.11-1 (2018-03-20) x86_64 GNU/Linux
so there are two problems here 1. suspend failures 2. ACPI errors. Then first please confirm if there is any change in the latest upstream kernel, because we've made some enhancements for both of the two issues. If the suspend problem still exists, please boot with kernel parameter "initcall_debug" and attach the full dmesg output after the failed suspend.
i'm currently running latest upstream kernel which is: Linux mkjlap 4.16.0-1-amd64 #1 SMP Debian 4.16.5-1 (2018-04-29) x86_64 GNU/Linux so far no wake-up issues... i'll keep you posted
no, when saying latest upstream kernel, I actually refer to 4.17-rcX e.g. you can download 4.17-rc5 kernel source from https://www.kernel.org/ and build your own kernel and see if the problem still exists.
ACPI failures (problem 2. mentioned in comment #4) have been confirmed fixed in 4.17-rc5 on bug https://bugzilla.kernel.org/show_bug.cgi?id=199295
as both the wakeup and the ACPI error issues are gone, bug closed.
