And PCI_EXP_CAP_CONFIG always FAIL here on RHEL or Fedora, the log is like:
[ 4668.373058] ltp_tpci: incorrect val read. PCIE driver/device not installed: '335609857'
Could you please investigate this?

Android is increasing in popularity, but the open development platform that
developers love is also attractive to malware creators. Download this white
paper to learn more about secure code signing practices that can help keep
