You can run "dmesg > dmesg.log" on the running kernel. And you can get two outputs. You can strip the time prefix from there by some script for easier comparison. > >> And, have you tested the revert? > I don't know how to do that. > > If you can point me to some doc, it would be nice. Have you ever built a kernel by yourself? If yes, it should be just a git revert of the suggested commit and rebuild / retest. If not, which (distro) kernel are you using? Usually you can ask distro people to build a test kernel. In general, please be more specific about your system and configuration. Takashi
