I have simply no idea what's going here :-(

Everything works fine on 32-bit dual xeon machine with card inserted into PCI 
slot. Here in new dual core opteron machine the card sits in PCI-X slot. It's 
Thunder K8SRE S2891 mainboard, Transport GT24 B2891 1U barebone, Tyan M2075 
riser card, 2 x Opteron 270, 6GB ram.

Note that booting with 32-bit kernel (which works fine on Xeon system) doesn't 
cure the problem on Opteron system. Booting 64bit 2.6.18rc4 kernel with 
mem=3G also doesn't fix anything.

/t is on tmpfs, /dev/sda2 in on FC array. Reading the same data several times 
and I get different md5sum results each time, see below.

How I can track where corruption occurs?

[root@pldmachine /t]# dd if=/dev/sda2 of=test-from-sda2-2 bs=1M count=1024
1024+0 records in
1024+0 records out
[root@pldmachine /t]# md5sum test-from-sda2-2
90b831662a5d3bd2501028eee3c00264  test-from-sda2-2
[root@pldmachine /t]# rm test-from-sda2-2
[root@pldmachine /t]# dd if=/dev/sda2 of=test-from-sda2-2 bs=1M count=1024
1024+0 records in
1024+0 records out
[root@pldmachine /t]# md5sum test-from-sda2-2
c06dadfc0726aa07cccdfbe7804e646f  test-from-sda2-2
[root@pldmachine /t]# rm test-from-sda2-2
[root@pldmachine /t]# dd if=/dev/sda2 of=test-from-sda2-2 bs=1M count=1024
1024+0 records in
1024+0 records out
[root@pldmachine /t]# md5sum test-from-sda2-2
06d61f81245bd242e9420277cfca65e4  test-from-sda2-2

dd'ing over tmpfs only is fine of course:
[root@pldmachine /t]# md5sum tmpfs-test
ddaaa7eb8da403f6079c55b1391ee1e3  tmpfs-test
[root@pldmachine /t]# rm tmpfs-test
[root@pldmachine /t]# dd if=test of=tmpfs-test bs=1M count=1024
1024+0 records in
1024+0 records out
[root@pldmachine /t]# md5sum tmpfs-test
ddaaa7eb8da403f6079c55b1391ee1e3  tmpfs-test
[root@pldmachine /t]# rm tmpfs-test
[root@pldmachine /t]# dd if=test of=tmpfs-test bs=1M count=1024
1024+0 records in
1024+0 records out
[root@pldmachine /t]# md5sum tmpfs-test
ddaaa7eb8da403f6079c55b1391ee1e3  tmpfs-test

btw. there is a "8131 Errata 56 PCLK" option in BIOS which is related to 
AMD-8131 Errata 56. This option is needed for ,, four-function PCI-X cards''. 
What's is four-function PCI-X card ? Card which is visible in lspci as 4 
devices? (This option also doesn't fix the problem unfortunately).
