Big thanks to Thorsten who suggested I look at the following: https://lore.kernel.org/all/20240123021155.2775-1-mario.limonciello@xxxxxxx/ https://lore.kernel.org/all/CABXGCsM2VLs489CH-vF-1539-s3in37=bwuOWtoeeE+q26zE+Q@xxxxxxxxxxxxxx/ Instead of further bisection I've applied Mario's revert from the first link on top of 6.8-rc1 and the issue seems gone for me now.
