Comment 104 for bug 1521173

I have experienced the same bug on my laptop HP - Pavilion and I think the problem is in compatibility between Wireless Card RTL8723BE PCIe and the linux kernal
causing it to infinitely log a PCIe Error on every boot/reboot of the system which cause a huge log files size on the disk!

I 'm not with the approach to suppress the warning on start up using grub defaults parameters (pci=nomsi and pci=noaer) .. I think this may endanger the system if a serious error/problem arises in the future and anyway the wifi card doesn't function properly due to the error.

So I think it might better to disable it permanently and use another wifi drive ( for example: usb adapter )
# Of course this is a "temp" solution until there is a fix to the kernal regarding this matter, but it will do the trick

Steps:
# In /etc/modprobe.d/blacklist.conf add this line at the end of the file then reboot the system
blacklist rtl8723be

# After rebooting to make sure the driver is disabled execute this
lsmod | grep rtl

# To get the kernal module related to the card name simply execute
lspci -nnk
