hi folks,

two weeks ago, i updated my truecrypt from version 6.0a to 6.2, unsuspecting what problem are gonna hit my face...
at the weekend i restartet the machine and tried to mount my crypted partitions, all partitions with a disc space < 2TB are mounting and working fine, but the truecypted partition greater than 2 TB (EXT4) failes with following message


Error: Kernel cryptographic service test failed. The cryptographic service of your kernel most likely does not support volumes larger than 2 TB.

- Try upgrading your kernel.
- Disable use of the kernel cryptographic services in the preferences.

i upgraded my kernel to, with no affect...

then i disabled the kernel cryptographic service with the -m=nokernelcrypto argument. well this works, but the partition is now mounted over the /dev/loop device and when i try to copy some files the message log gives me a bunch of these errors

EXT4-fs error (device loop0): mb_free_blocks: double-free of inode 0's block 600731091(bit 28115 in group 18332)
EXT4-fs error (device loop0): mb_free_blocks: double-free of inode 0's block 600731092(bit 28116 in group 18332)
EXT4-fs error (device loop0): mb_free_blocks: double-free of inode 0's block 600731093(bit 28117 in group 18332)

does anybody know what iam doing wrong or know a sugesstion? this would very helpful.... :?:

thnx and greetz

kk, seems to be no one get this problem...maybe there aren't so many truecrypt users here and all fellaz usin dmcrpyt+luks, who knows....

if anybody is interested, i downgraded to truecrypt-6.0a, emerged the sys-fs/e2fsprogs-1.41.4, doin fsck.ext4 and all things are workin fine again...the 3 tb partition is mountin correctly with no errors and over the device-mapper... :P

if somebody gets compile errors on truecrypt-6.2 x86_64, look here
