I recently bought the following laptop:
Asus VivoBook X542UQ-DM148T - 15.6" (i7-7500U/8GB/256GB/GT 940MX 2GB)
It came pre-installed with Win10 and I did a fresh install of Ubuntu 16.04 LTS. The screen was flickering for some reason and installing Ubuntu 17.04 fixed the issue.
The real problem is that when I'm booting the laptop, the following error is being shown on my screen:
[ 12.866073] pcieport 0000:00:1c.5: can't find device of ID00e5
[ 12.898481] pcieport 0000:00:1c.5: AER: Multiple Corrected error received: id=00e5
[ 12.898488] pcieport 0000:00:1c.5: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e5(Receiver ID)
[ 12.898491] pcieport 0000:00:1c.5: device [8086:9d15] error status/mask=00002041/00002000
[ 12.898492] pcieport 0000:00:1c.5: [ 0] Receiver Error (First)
[ 12.898493] pcieport 0000:00:1c.5: [ 6] Bad TLP
I know that this error can be hid with one of the following kernel boot arguments:
pci=nomsi / pci=noaer / pcie_aspm=off / pci=nommconf.
The weird thing is that the above output is only being shown when the laptop is on AC Power (charging). When the laptop is not connected to AC (battery-mode), it has performance issues (slow boot and slow application launching). I was trying all day long to fix the problem. I removed everything that had to do with power-saving, reinstalled, re-tweaked for performance but had no luck. While diagnosing, I had the idea to benchmark the "M2 SATA-3 SSD" that my laptop had. The results are:
* On AC Power: 522MB/s (READ) | 416MB/s (WRITE)
* On Battery Power: 32MB/s (READ) | 31MB/s (WRITE)
This explains everyting. That's why I'm having a slow boot and slow application launching!
Commands "lspci" and "dmesg" say that the error comes from the following device:
00:1c.5 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #6 (rev f1)
I will attach lspci and dmesg output on a tar.gz file.

I recently bought the following laptop:
Asus VivoBook X542UQ-DM148T - 15.6" (i7-7500U/8GB/256GB/GT 940MX 2GB)
It came pre-installed with Win10 and I did a fresh install of Ubuntu 16.04 LTS. The screen was flickering for some reason and installing Ubuntu 17.04 fixed the issue.
The real problem is that when I'm booting the laptop, the following error is being shown on my screen:
[ 12.866073] pcieport 0000:00:1c.5: can't find device of ID00e5
[ 12.898481] pcieport 0000:00:1c.5: AER: Multiple Corrected error received: id=00e5
[ 12.898488] pcieport 0000:00:1c.5: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e5(Receiver ID)
[ 12.898491] pcieport 0000:00:1c.5: device [8086:9d15] error status/mask=00002041/00002000
[ 12.898492] pcieport 0000:00:1c.5: [ 0] Receiver Error (First)
[ 12.898493] pcieport 0000:00:1c.5: [ 6] Bad TLP
I know that this error can be hid with one of the following kernel boot arguments:
pci=nomsi / pci=noaer / pcie_aspm=off / pci=nommconf.
The weird thing is that the above output is only being shown when the laptop is on AC Power (charging). When the laptop is not connected to AC (battery-mode), it has performance issues (slow boot and slow application launching). I was trying all day long to fix the problem. I removed everything that had to do with power-saving, reinstalled, re-tweaked for performance, tried different kernels but had no luck. While diagnosing, I had the idea to benchmark the "M2 SATA-3 SSD" that my laptop had. The results are:
* On AC Power: 522MB/s (READ) | 416MB/s (WRITE)
* On Battery Power: 32MB/s (READ) | 31MB/s (WRITE)
This explains everyting. That's why I'm having a slow boot and slow application launching!
Commands "lspci" and "dmesg" say that the error comes from the following device:
00:1c.5 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #6 (rev f1)
I will attach lspci and dmesg output on a tar.gz file.
--------------------------------------------------------------------------
UPDATE: When the laptop is fully charged and still on AC (but not charging since it is 100% charged), the errors appear again but the SSD speed is normal (~500 Read/Write).
--------------------------------------------------------------------------
UPDATE: I installed 'tlp' Advanced Power Management package and when using the command 'tlp ac', the SSD speed gets back to normal! The option does not persist across reboots.
