Kernel)
Platform: All
OS/Version: Linux

Includes kern.log, linux-image.crash-log and file with system information
* Overview: More detailed restatement of summary.
I have 2 encrypted drives, the Kernel becomes unstable or I get Kernel Panic
when I'm using one of this drives. This means, if I try to copy files from one
encrypted drive to another I get in the most cases Kernel Panic after a short
time.
If accessing more than one application files from an encrypted drive, I get
often the message that the system might become unstable and I need to reboot
because I can't access the encrypted drive any more. The same when I try to
force a file system check with fsck, I get every time the message that the
system might become unstable.
* Steps to Reproduce: Minimized, easy-to-follow steps that will trigger the
bug. Include any special setup steps.
The easiest way to reproduce is to check the file system with fsck:
1) Mount the volume with the TrueCrypt GUI (check under "Filesystem: Do not
mount")
2) Force file check with "sudo fsck -f /dev/mapper/truecrypt1"
3) After a short while I get a new icon in the tray with the message "Your
system might become unstable now and might need to be restarted."
* Actual Results: What the application did after performing the above steps.
The Kernel becomes unstable (Your system might become unstable now and might
need to be restarted.) and I can't access the drive until reboot.
* Expected Results: What the application should have done, were the bug not
present.
fsck should check the mapped drive and should fix errors if any.
* Build Date & Platform: Date and platform of the build in which you first
encountered the bug.
I'm running Ubuntu 10.04 beta with mainline Kernel.
* Additional Builds and Platforms: Whether or not the bug takes place on other
platforms (or browsers, if applicable).
The last Kernel without problems was 2.6.28.8 (Ubuntu 9.04), all newer Kernels
crashing my system.
* Additional Information: Any other useful information.
I'm using TrueCrypt 6.3a, AES Encryption and the drives are formatted with
ext4.
