r367998 adds rtsx driver for card reader, seems to work for me on P51
(as in "detected and does not panic", I don't have any cards around to
really test it):
rtsx0@pci0:63:0:0: class=0xff0000 rev=0x01 hdr=0x00 vendor=0x10ec
device=0x525a subvendor=0x17aa subdevice=0x224d
vendor = 'Realtek Semiconductor Co., Ltd.'
device = 'RTS525A PCI Express Card Reader'
To confirm the issue is indeed in rtsx, does disabling the card reader
in bios help? If it does, what is the device exactly (`pciconf -lv`
when booted on pre-r367998)?
