The kernel panic happens immediately after the SDHC card is inserted, reproducibility is 100%. If the system boots up with the card already inserted, it will crash as soon as sdhci_pci module is loaded. If the module is unloaded/blacklisted, obviously, nothing happens as the system does not see the MMC card reader. The machine is Lenovo thinkpad T-510 laptop with Intel Westmere CPU/3400 series chipset running 64-bit kernel 4.3.0.
