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

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. -- You

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.

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

I modified tlp for max performance but tlp starts only when desktop boots. So, kernel boot is slow. 2017-11-02 8:57 GMT+02:00 Kai-Heng Feng : > Did you change the SATA link power management or other settings? > > Can you attach the diff of your TLP setting? > > -- >

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? -- You received this bug notification because you are a member of Kernel Packages, which is

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. ** Description changed: I recently bought the following laptop: Asus VivoBook X542UQ-DM148T - 15.6"

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

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
