Thank you Bisect done - This is result: ---------------------------------------------------------------- 69304c8d285b77c9a56d68f5ddb2558f27abf406 is the first bad commit commit 69304c8d285b77c9a56d68f5ddb2558f27abf406 Author: Ricky WU Date: Tue Jul 25 09:10:54 2023 +0000 misc: rtsx: judge ASPM Mode to set PETXCFG Reg commit 101bd907b4244a726980ee67f95ed9cafab6ff7a upstream. ASPM Mode is ASPM_MODE_CFG need to judge the value of clkreq_0 to set HIGH or LOW, if the ASPM Mode is ASPM_MODE_REG always set to HIGH during the initialization.
