I wanted to test software raid, but since I've run out of physical partitions I created two loopback devices on two ext3 partitions, each one 2 GB. I used mdadm 1.5.0 to create a RAID1 disk, and made an ext2 fs on it. While copying a 700MB file to it, the following appeared in the kernel log. Checksumming the copied file gave a different value than the original file, and checksumming it again gave a third value.

I'm using kernel 2.4.24, on an AMD Duron 1.3GHz with 256 MB memory and 256 MB swap. I've run memtest86 3.0 for a day on the machine without problems. I searched in the archives, but could only find something that was supposed to be fixed in 2.4.10. I've attached my .config.
