Hi, Thank you Rafael. I tried with linux-2.6.14.5 and it worked. The steps I followed are 1. Add the following line as kernel parameter in grub.conf resume=/dev/hdb2 // /dev/hdb2 is my swap partition 2. Then I did the following echo shutdown > /sys/power/disk echo disk > /sys/power/state This worked.But after resuming I checked my /var/log/message and got the following message which cotains the oops messages as well. ****************************************** Jan 4 10:51:45 rasmit kernel: Stopping tasks: ======================================================================| Jan 4 10:51:47 rasmit

The resume= is necessary for resume anyway, because it is done before swap partitions are activated.
