Intel 8260 card gets dropped from system 'randomly'

Ok, so I have this 'new' Gigabyte Aero 14k laptop and I like it a lot.  Somewhere around kernel 4.14 my Intel 8260 WLAN card started to become disconnected from the PCI bus every once in a while, most notably when  the laptop decides to save some power and puts devices to sleep. Using either laptop-mode or tlp shows the same effect.  The effect is worse when the battery is below 15%, at this time WLAN becomes unusable and I can only resurrect it by invoking:

# remove pci device, you might have to change the 03:00.0 part to yours
sudo echo "1" > /sys/bus/pci/devices/0000:03:00.0/remove
sleep 2
# rescan for devices
sudo echo "1" > /sys/bus/pci/rescan

journalctl always shows entries like this (Full log after resuming from suspend: http://ix.io/1pSl, lspci -v output: http://ix.io/1pSm, /etc/default/tlp: http://ix.io/1pSo):

After searching the BBS, the Internet, the kernel bug database I have not found any solution yet.  I am grateful for any pointers to more information, maybe proper configurations of tlp (which I actually use) or kernel boot parameters.  And yes, I could replace the card, but when I dual boot into windows it works just fine ...
