I'm using FC3 with Kernel 2.6.12-1.1376.
After few hours file system on /dev/hda8 EXT3 partition has a problem so it
remounted in only read mode.
I tried several times to run fsck on this partition and I also tried to
remount fs in a new partition, but it happened nothing !
I have this message:

That block number is 0x8000000 in hex. It's a single-bit flip error;
that strongly sounds like hardware, and I'd run memtest86 on that box
next.

What do you mean? fsck found nothing wrong? remount failed? You _did_
unmount before fscking, did you?

I run memtest86 and It gives errors.
I removed the installed 256 MB RAM of 512 MB and now PC works.

thanks
