[Bug 546316] Re: umount caused kernel oops after suspend/resume with encrypted SD card

[Likewise]

I have a similar issue as the reporter. I was trying to insert an SD
card into my monitor, I was fiddling a bit finding for correct
insertion. SD Card showed up in Nautilus and I was looking into "dmesg"
to see what "sdX" device it had gotten. Then I saw the WARNING.

First two lines included, so that we see there was no logged activity
before.
