Comment # 22 on bug 1097605 from Stakanov Schufter

I have now installed an I am running:
uname -a
Linux linux-hk9l.suse 4.4.138-9.g89489c7-default #1 SMP Wed Jun 27 05:04:06 UTC
2018 (89489c7) x86_64 x86_64 x86_64 GNU/Linux
Observations:
a) compared to the original Kernel of Leap 15 the working temperature of the
machine is astonishingly lower. 
b) wlan does not crash and is functional, also after suspend to disk and after
hours of being idle. 
c) the memory leak that I am experiencing with akonadi/kontakt when running
idle (up to 8 GB memory + 3 GB of Swap before crashing or emergency shutdown
for temperature) is no present when running the old kernel. 
Memory will be 2.5 with three users open and two instances kontact. With FF it
will take (for one user) 3,5 GB. And it is stable when being idle, no new
consumption. 
d) with the leak, system will get sluggish or not react any more. Also this is
not present with the old kernel. 
The 42.3 kernel is, for what ever reason, for the Lenovo X201, really
noteworthy superior for what is stability and power.

The wlan after suspend is able to reconnect (unlike with the original kernel).
However the bug with wallet not opening is present as well, thus you need to
log out with that user and log in to get the wallet prompt. After that it
reconnects normally, even after suspend to disk. With the new kernel this will
not happen.

e) occasional system freezes that require hard reboot, do not happen with the
older kernel.
