It's https://lore.kernel.org/linux-cifs/afbccb0c466888faa0e4753094e8ba09ed16dc51.ca...@amazon.com/ But I fear that will be lost due to missing CC's to others. So have just replied with regressions list as wel in https://lore.kernel.org/regressions/zzhrpnj3zxmr8...@eldamar.lan/ As this does not happen with upper stable series, I guess some requisite commit is missing. The mentioned commit from 6.7-rc5 was backported to 6.6.7 and 6.1.68, but it does not happen in current 6.6.9-1 as in unstable. Regards, Salvatore
