Just now I did the following experiment: I booted Linux 6.10 without "pcie_aspm=off", then I booted it with "pcie_aspm=off", then again without, etc. In total I did nearly 13 boots with "pcie_aspm=off" and nearly 13 boots without "pcie_aspm=off". All these boots were performed automatically by script using kexec. No hibernation was involved.
System was booted, then "sleep 60" was executed, then kexec booted again. Results are so: - All boots with "pcie_aspm=off" display no errors - 3 out of 13 boots without "pcie_aspm=off" display no errors. Other 10 boots show these "corrected error received" errors (at least one time). But number of these messages is small (say, 5 messages in one boot, i. e. in 60 seconds). (My practice shows that if you really want to see a LOT of these messages, you should do hibernate and then resume.) So, it seems that: - Debugging using "kexec" works - You don't need hibernate to reproduce this bug (but number of error messages will be small) - "pcie_aspm=off" makes messages disappear - There is a stable way to reproduce bug: boot 13 times using kexec. 10 times out of 13 you will see at least one message Ask me any questions. I'm ready to do other experiments, send any kind of logs, etc -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1521173 Title: AER: Corrected error received: id=00e0 Status in Linux: Unknown Status in linux package in Ubuntu: Triaged Status in linux source package in Xenial: Triaged Bug description: WORKAROUND: add pci=noaer to your kernel command line: 1) edit /etc/default/grub and and add pci=noaer to the line starting with GRUB_CMDLINE_LINUX_DEFAULT.
