Hi,

I have got syslog error that kernel is trying to mount partition with unknown file system:

The first case: "/dev/sde1" Partition is marked as bios-grub and should not be trying to be mounted by kernel.
The second case " /dev/sdf1" is used by truecrypt application . Kernel should not be trying to mount it.

P.S. Is it possible to tell to kernel not to trying mount some specific partition/s ? Like by some kernel parameter ...

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.17 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I have installed that kernel and did try twice to run it but it freeze. So, after log in - within couple of seconds the computer hang up. So , I cannot test it.
