Nevertheless, you should report it to linux-usb and linux-pci mailing lists, along with the oops stacktrace (under a new thread).

Yeah, i also my way around - not fiddle much with the cards and if they slip out during insertion, don't re-plug them too quickly (at least with the USB3 card and SATA card I had problems). BTW, if you remove a card, you are supposed to push the card into the slot so it gets ejected. Do not just pull it out (what I did in the beginnings). I was told that is not the right way (probably affects the PresDet status).
