VJ, this is not the first time similar inquiries have appeared here, and I encountered the same problem with a completely different hardware setup.  I saw this happening on a SCSI raid w/caching controller.  I discovered a work around by disabling cache writes to filesystem in the mount.  Some of the newer ide/sata drives are coming with large caches (~8meg), so it makes me wonder about a possible correlation there.  Maybe completely off target - just FYI...

I am running kernel "2.6.9-1.681_FC3" with "noapic nolapic acpi=off".
 

I ran Segate's own Seagate Tools for surface scan - No problem found.
I ran smartctl -t long /dev/hdh for SMART extensive test. No problems there either.
 
Any ideas???

Hi Paul,
    Thanks for the reply. Could you please tell me how to disable cache write in mount option? I tried man mount but could not find it.
