Package: linux-2.6
Version: 2.6.18.dfsg.1-12etch2
Severity: critical
This is also on the kernel's bugzilla (http://bugzilla.kernel.org/show_bug.cgi?id=7388
)
It happens at random interval (1 out of 20 times), when doing a "cryptsetup luksOpen". After that, as soon as the file (/dev/mapper/xxx) is accessed, the oops appears. I'm able to reproduce it easily.
Here's the message from the kernel :
