  It doesn't panic, boots and works more than 500 seconds :-)

Output is like this:

pcib2: <ACPI PCI-PCI bridge> at device 28.0 on pci0
pci2: <ACPI PCI bus> on pcib2
rtsx0: <2.0c Realtek RTS5227 PCI MMC/SD Card Reader> mem 0xf4500000-0xf4500fff at device 0.0 on pci2
rtsx0: Interrupt card inserted/removed
rtsx0: Card absent
rtsx0: Card absent
pcib3: <ACPI PCI-PCI bridge> at device 28.1 on pci0
pci3: <ACPI PCI bus> on pcib3

  (no visible pause between two "Card absent" lines).
