GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"
then I did
and hoped the error will be corrected and if not I will apply the other method to it i.e. "pci=noaer" but the ubuntu is stuck after initial loading at link to the stuck screen image, after long wait I have to turn off the laptop using the power button. I have also tried updating the
GRUB_CMDLINE_LINUX_DEFAULT with pci=noaer using "grub-> recovery-> resume".
Please help me with this, thanks. Other details: installed ubuntu 18.04LTS Laptop: asus
Edit: I think there's something wrong with my log files they have taken a whole lot space as I can see in recovery mode
79041M kern.log, 13508M kern.log.1, 61355M syslog, 17688M syslog.1,
the kern.log file is filled with that same PCie port error discussed above.
