I just stopped the following services and start them all again,

Code:
apmd,gpm,haldaemon,isdn,mcstrans,setroubleshoot,pcscd,mdmonitor,messagebus,microcode_ctl
And everything is fine now..


I thought the problem was due to the
Code:
gpm
service,but after I started it ,the problem still continued.So I started all the services those were stopped.

Sorry guys.

Today the same happens again 5 times.But today I somehow go to tty1 and get the error like this

Code:
dma_timer_expiry
  dma status == 0x21
What should be the reason behind this ??

DMA errors usually indicate a hard drive or controller problem. Which is why I asked for the file source/destination, since if you were copying from one drive to another, it could have been part of the issue.

check out the Meamory and PF usage of the system
 
check out the process just type the command ps -aux and you will get the information or type top just see which process is consuming most memory

Actually I made a lvm of 40GB as my Backup drive,this error caused yesterday during the following situations,

1>>While transfering data from root's home dir to that lvm partition

2>>while transfering from lvm partition to external pendrive.
