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

Wed Mar 24 19:46:23 UTC 2010

Public bug reported:

I have an HP nx8220 laptop with a built in SD card slot. Suspending and
resuming the laptop with a mounted encrypted SD card resulted in a
kernel oops:

Mar 24 18:10:09 cygnus kernel: [19358.108509] lost page write due to I/O error on dm-0

I can't recall the exact sequence of events, but I believe it was:

* Inserted SD card. Prompted for passphrase. Entered and selected "remember passphrase forever"
* Icon for SD card appeared on desktop with open padlock icon. Successfully accessed files.
* Suspended and resumed laptop.
* Was prompted again for passphrase for SD card. Again entered and selected "remember passphrase forever"
* Got an error message dialog saying something to the effect that the file system was already mounted.
* Icon for SD card appeared on desktop *without* padlock icon.
* Right clicked on SD card icon and unmounted the drive.
