Steve, I can confirm that in my setup.

Test is easy, as described by Scott.

I've copied over the first iso I found on my PC to my fileserver running an ext4 /data partition. Then I had some fun with md5sum:

kai@woodstock:/data/iso$ md5sum en_win_xp_pro_n.iso
138468d380b84e6b9e9a8648efb97143 en_win_xp_pro_n.iso
kai@woodstock:/data/iso$ md5sum en_win_xp_pro_n.iso
d6b2bc09fc4df1876005f20b62364f6e en_win_xp_pro_n.iso
kai@woodstock:/data/iso$ sync
kai@woodstock:/data/iso$ md5sum en_win_xp_pro_n.iso

kai@woodstock:/data/iso$ md5sum en_win_xp_pro_n.iso

kai@woodstock:/data/iso$ md5sum en_win_xp_pro_n.iso
f8e682be3590d48e0c266d15a804e3af en_win_xp_pro_n.iso
kai@woodstock:/data/iso$ md5sum en_win_xp_pro_n.iso
d11a45c61466f2b22757e0e449e2fe90 en_win_xp_pro_n.iso
kai@woodstock:/data/iso$ md5sum en_win_xp_pro_n.iso
d11a45c61466f2b22757e0e449e2fe90 en_win_xp_pro_n.iso

Note that it seems to stabilized on d11a45c61466f2b22757e0e449e2fe90 after bouncing off from there once. Also note that calling sync seems to have no effect on the bug.

That's certainly a fun one.
