Looks like there PCIe errors detected
DevSta: CorrErr+ **UncorrErr+ FatalErr- UnsuppReq+ AuxPwr+ TransPend-
Would you please attach full dmesg log and full lspci -vvv (run as root) after
issue occurs.
Please also attach your kernel .config.
Does this issue happen after you upgrade kernel?
Few things to try,
please load AER module and see if it logs any errors into log.
Does BIOS log reports any machine check errors?
Try disable TSO.
