The below syslogs ( PCIe Bus Error: severity=Corrected ) are reported after version upgrade ,and this kind of logs would print within 7 days after chassis reload. Jul 22 18:23:57.032: %IOSXE-3-PLATFORM: R0/0: kernel: Octeon 0000:09:00.0: AER: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID) Jul 22 18:23:57.032: %IOSXE-3-PLATFORM: R0/0: kernel: Octeon 0000:09:00.0: AER: device [177d:9700] error status/mask=00002001/00006000 Aug 23 21:09:53.147: %SYS-6-LOGOUT: User networkcell has exited tty session 866(10.63.255.11) Aug 24 10:57:07.390: %IOSXE-3-PLATFORM: R0/0: kernel: Octeon 0000:09:00.1: AER: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)

We can change the below value( step 3-3) by accessing to the shell as workaround, but this value will be reset after a chassis reload.

After kernel 5.15 upgrade(happened on 17.10), these PCIE correctable error print are already muted by kernel. So these error print will not be seen on IOS version 17.10 and later. Fixed version including: 17.10.1, 17.11.1, 17.12.1 and later releases.
