Hi,

I just updated the Kernel to 2.4.23-rc1 with the xfs snapshot from 11/11/2003. 
The behavior changed a bit .. the errors are reduced but still there:

[root@mss archive]# dd if=/dev/zero of=testfile1 bs=1M count=200
200+0 Records in
200+0 Records out
[root@mss archive]# dd if=/dev/zero of=testfile2 bs=1M count=200
200+0 Records in
200+0 Records out
[root@mss archive]# compare testfile1 testfile2
files differ at byte 59244560  (0x3880010)      0x7f != 0x00    ^?    ^@
