What is PCIe error?
The PCIe Bus Error is basically the Linux kernel reporting the hardware issue. This error reporting turns into nightmare because of the frequency of error messages generated by the system.
What is a PCIe analyzer?
The Keysight U4301B PCI Express (PCIe) analyzer combines accurate probing technology with flexible hardware architecture. This PCIe 3.0 analyzer uses Keysight’s unique Equalization Snoop Probe (ESP) technology, allowing you to match the algorithm to the type of channel the protocol analyzer is monitoring.
What is PCIe advanced error reporting?
AER (Advanced Error Reporting) is an optional PCI Express feature that allows for more enhanced reporting and control of errors than the basic error reporting scheme. AER errors are categorized as either correctable or uncorrectable.
Why does my PC need to restart for PCI bus?
Restart required PCI bus error can be caused by incompatible hardware, and if you installed any new hardware recently, be sure to remove it or replace it. If the new hardware isn’t fully compatible with your PC that can lead to system instability and BSoD errors, so be sure to remove any recently installed hardware.

What is PCIe completion timeout?
Completion Time-out: As per the PCIe, the completion must be returned in specified time for the request else there will be completion timeout. The completion time-out mechanism is implemented by any device that initiates requests and require completions to be returned.
What is Bus Error in Linux?
In computing, a bus error is a fault raised by hardware, notifying an operating system (OS) that a process is trying to access memory that the CPU cannot physically address: an invalid address for the address bus, hence the name.
How do you capture a PCIe trace?
Capturing the Trace Begin with the PCIe link completely powered down. Click the record button, and then boot up the system we want to analyze. We will immediately see the first 10% (the same amount we allocated for pre-trigger in our recording options) of the buffer fill with training sequences.

Add pci=noaer in this line. AER stands for Advanced Error Reporting and ‘noaer’ asks the kernel to not use/log Advanced Error Reporting. The changed line should look like this: Restart Ubuntu and you shouldn’t see the ‘PCIe Bus Error severity Corrected messages’ anymore.
How to disable PCIe Error Reporting in Grub?
If your system works fine, your main concern should be that too much of error reporting doesn’t eat up the disk space. In that regard, you can change the Linux kernel parameter and ask it to stop reporting the PCIe errors. To do that, you need to edit the grub configuration. Basically, you just have to use a text editor for editing the file.
