Mounting problem



Hi folks,

For unknown cause I encounter following mounting problem;

# /mnt/hda8
mount: wrong fs type, bad option, bad superblock on /dev/hda8,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so


# dmesg | tail
via82cxxx: timeout while reading AC97 codec (0x9A0000)

EXT3-fs: hda8: couldn't mount because of unsupported optional features
(2000200).

Previously this partition can be mounted without problem.  I also tried
adding -t ext3 without result still having the same warning.


# e2fsck -f /dev/hda8
e2fsck 1.38 (30-Jun-2005)
e2fsck: Filesystem revision too high while trying to open dev/hda8
The filesystem revision is apparently too high for this version of
e2fsck.  (Or the filesystem superblock is corrupt)

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate
superblock:
    e2fsck -b 8193 <device>


# e2fsck -f 8193 /dev/hda8
Usage: e2fsck [-panyrcdfvstDFSV] [-b superblock] [-B blocksize]
                [-I inode_buffer_blocks] [-P process_inode_size]
                [-l|-L bad_blocks_file] [-C fd] [-j external_journal]
                [-E extended-options] device

Emergency help:
 -p                   Automatic repair (no questions)
 -n                   Make no changes to the filesystem
 -y                   Assume "yes" to all questions
 -c                   Check for bad blocks and add them to the badblock
list
 -f                   Force checking even if filesystem is marked clean
 -v                   Be verbose
 -b superblock        Use alternative superblock
 -B blocksize         Force blocksize when looking for superblock
 -j external_journal  Set location of the external journal
 -l bad_blocks_file   Add to badblocks list
 -L bad_blocks_file   Set badblocks list


Please advise how to fix the problem.  TIA
