[Kernel-packages] [Bug 1726159] Re: PCIe BUS Error causing really slow laptop performance

2018-06-10 Thread George Mathioudakis

I fixed the slow booting problem by editing "/etc/hdparm.conf" and
changing "apm_battery" value to "255". Now my laptop boots normally on
battery mode (same speed as plugged in AC).

Now, for the AER problem, just ignore it. Add pci=noaer as kernel boot 
parameter.
I hope I helped.

  PCIe BUS Error causing really slow laptop performance

Status in linux package in Ubuntu:

Bug description:
  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 :00:1c.5: can't find device of ID00e5
  [   12.898481] pcieport :00:1c.5: AER: Multiple Corrected error received: 
id=00e5
  [   12.898488] pcieport :00:1c.5: PCIe Bus Error: severity=Corrected, 
type=Physical Layer, id=00e5(Receiver ID)
  [   12.898491] pcieport :00:1c.5:   device [8086:9d15] error 
status/mask=2041/2000
  [   12.898492] pcieport :00:1c.5:[ 0] Receiver Error (First)
  [   12.898493] pcieport :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.

[Kernel-packages] [Bug 1726159] Re: PCIe BUS Error causing really slow laptop performance

2017-11-10 Thread George Mathioudakis

Very Important Info: I inserted my Samsung 850 EVO 250GB SSD on my
laptop's HDD slot and on battery power, with TLP off, it runs on normal
speed 550MB/S Read/Write! My primary M.2 SSD "Micron 1100 250GB" is
still running on 32MB/S Read/Write. That means Micron SSD is checking
for battery/ac mode.

I modified tlp for max performance but tlp starts only when desktop boots.
So, kernel boot is slow.

[Kernel-packages] [Bug 1726159] Re: PCIe BUS Error causing really slow laptop performance

2017-10-31 Thread George Mathioudakis

Changing TLP config values did the job. But, tlp is making changes only
when the desktop appears. How can I change kernel values to start on max
performance? What value changes tlp does to kernel?

  PCIe BUS Error causing really slow laptop performance

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  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 :00:1c.5: can't find device of ID00e5
  [   12.898481] pcieport :00:1c.5: AER: Multiple Corrected error received: 
id=00e5
  [   12.898488] pcieport :00:1c.5: PCIe Bus Error: severity=Corrected, 
type=Physical Layer, id=00e5(Receiver ID)
  [   12.898491] pcieport :00:1c.5:   device [8086:9d15] error 
status/mask=2041/2000
  [   12.898492] pcieport :00:1c.5:[ 0] Receiver Error (First)
  [   12.898493] pcieport :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.

[Kernel-packages] [Bug 1726159] Re: PCIe BUS Error causing really slow laptop performance

2017-10-26 Thread George Mathioudakis

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).

I don't think that the CPU frequency has a limit when on battery-mode.
The problem is related with my stock SSD (the laptop came with).

** Description changed:

  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 :00:1c.5: can't find device of ID00e5
  [   12.898481] pcieport :00:1c.5: AER: Multiple Corrected error received: 
id=00e5
  [   12.898488] pcieport :00:1c.5: PCIe Bus Error: severity=Corrected, 
type=Physical Layer, id=00e5(Receiver ID)
  [   12.898491] pcieport :00:1c.5:   device [8086:9d15] error 
status/mask=2041/2000
  [   12.898492] pcieport :00:1c.5:[ 0] Receiver Error (First)
  [   12.898493] pcieport :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.

[Kernel-packages] [Bug 1726159] Re: PCIe BUS Error causing really slow laptop performance

2017-10-24 Thread George Mathioudakis

I blacklisted ath10k_pci by adding "modprobe.blacklist=ath10k_pci" as a
kernel parameter.

The errors are gone, but the slow Read/Write problem still persists.
Also, the Wi-Fi (as expected) is going completely off.

Reminder: The erros are not showing on the boot screen or system logs
when connected to AC power and the SSD speeds are normal (~500
Read/Write)

  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

  I will attach lspci and dmesg output on a tar.gz file.
