Any error reported? > Hi Sathyanarayanan,
No error reports yet, I just changes the behavior back to what it was before commit e7b0b847de6d ("PCI/AER: Clear only ERR_NONFATAL bits during non-fatal recovery"), because this commit change the original function in commit bf2a952d31d2 ("NTB: Add IDT 89HPESxNTx PCIe-switches support").
