I face the same issue on my HP ProBook 440 G4. And my laptop has the same crappy RTL8723BE WiFi chip. But the PCIe Bus Error and Wifi problems you might be facing are separate issues. The PCI bus errors can be cured by adding pci=noaer to the kernel args as mentioned by many users in the thread above. AER spams this error so much that it overwhelms your disk and so logging in becomes near impossible. Easiest option for you would be adding this kernel arg when you hit grub during boot.
If you have Wifi signal issues on Linux then that's due to a quirk with this 8723 chip. Don't want to sidetrack this bug thread so I'll just ask you to search for the "RTL8723BE ant_sel" fix. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1726159 Title: PCIe BUS Error causing really slow laptop performance To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1726159/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
