[Pkg-utopia-maintainers] Bug#758932: udisksd: Disconnecting USB disk results in kernel crash

[Chris Tillman]

Package: udisks2
Version: 2.1.3-2
Severity: critical
File: udisksd
Justification: breaks the whole system

Dear Maintainer,

   * What led up to the situation? Disconnecting a USB drive
   * What exactly did you do (or not do) that was effective (or
     ineffective)? Could not regain access to the system, had to cold boot

Here are entries from syslog just after disconnecting the drive until the
kernel crash.

device sdb10, logical block 2
Aug 23 10:01:37 121-73-239-129 kernel: [143836.764474] lost page write due to
I/O error on sdb10

I believe this occurred because I had a terminal window open in one of the
directories on the USB mounted drive when I disconnected it (the 19GB volume
which was sdb10).
