I'm getting following error message at the system boot up. The system takes long time to start and I could not understand what it's saying and why. The os has recently been installed(3 weeks ago). The following are the last few line of /var/log/dmesg file. Please any one let me know if it could be resolved. Thank you!

Maybe hardware issue: SATA-cable? Any reason for installing 9.10 and not 10.04 LTS? –  Takkat Jan 18 '11 at 11:32
    
9.10 worked fine for the web developers so can't trust new releases 10.04 & 10.10 –  user3215 Jan 18 '11 at 15:00
    
So my first try is checking the sata cable –  user3215 Jan 18 '11 at 15:01

In 9.10 there are some still open bugs related to ata disk access. As support for 9.10 ends in April 2011 they may never be fixed. If changing cable doesn't help I recommend you try to get your applications running on 10.04 rather than filing a bug against 9.10. –  Takkat Jan 18 '11 at 15:24

This looks to be a harddrive error(because of ATA errors). What worked for me when I had an error like this is loading to a bootable cd and runing

fsck /dev/sda1

This fix the filesystem problem which was preventing my friends system from booting.

I would also run smart test on the drive to see if it needs replacing.

I should try this... –  user3215 Jan 21 '11 at 0:16
    
Yeah, e2fsck -c /dev/sda1, sda2, sda3... tried to fix it and the system booting normally for now. But I still doubt the HD, as it said HD has many bad blocks and should be replaced; while fixing the bad blocks. –  user3215 Jan 24 '11 at 4:44

I can only guess that the issue is hardware related since the log shows very terminal errors contacting the disk. Check your computer's internal connections.

If it's not that, then you have serious issues which need to be reported as bugs (but check cables first). There is no answer really to such issues as if it is a bug, it just needs to be fixed by someone. See here for details:

Filing a bug against 9.10 has little chance to get noticed or even fixed if later releases are not affected. –  Takkat Jan 18 '11 at 15:25
    
Then the bug's been fixed. –  Martin Owens -doctormo- Jan 18 '11 at 17:11
    
If the bug was fixed e.g. in kernel 2.6.32-xx or later then the fix will never reach 9.10. using kernel 2.6.31-xx –  Takkat Jan 18 '11 at 20:52

Yes, and thus using 9.10 is impossible and should not be considered. –  Martin Owens -doctormo- Jan 18 '11 at 23:45
