It be great if narrow it more down, so we know > it for example regressed in 6.2-rc7. Not easy, unfortunately. The official TW kernel moved to a newer version only after the final release. Although the rc kernel packages are provided as unofficial packages, they are transient and go away at each update, so we have no archives for testing the older ones. Or, if you can suggest some commit to be tested for revert, I can create a test kernel package at any time. thanks, Takashi _______________________________________________ Intel-wired-lan mailing list Intel-wired-lan@osuosl.org https://lists.osuosl.org/mailman/listinfo/intel-wired-lan
