Debian on CF card causes File System Errors after a while!!


I have got Debian running on a CF card.. The device is a low capacity (in terms of processing power) network device (like a minipc, embedded device)..

I am running read and write operations frequently and I realized that there seems to become filesystem errors..

This thread mentions something:

"There is a know problem with some 64bit mobos where under conditions of high network and disk activity, they just wig out and start scribbling over the hard drive. When in this state the damage doesn't correlate with recent writes, it just seems to spray the disk. It seems to be something to do with IOMMU and/or ACPI. The more recent the kernel version, the less likely it seems to be to happen."

Anybody know what is the exact cause for this? And much more importantly how to prevent this problem from happenning?

The network will be widespread and I have realized this problem at the pilot study. I will not be able to go ahead and do manual operations when the network is formed..

I am now stuck!!

by the way the problem may or may not be related with the thread I quoted. my device does not have 64bit mobo and disk activity is 10-20 kilobyte per min. If anybody encountered a similar problem with cf cards or debian or read write operations please help..
