The difference is, I can reproduce this with the simplest possible setup; I have an older Asus Mobo with an AMD1.33GHz CPU, 1 Promise SX4 SATA controller (0000:00:0a.0 RAID bus controller: Promise Technology, Inc.: Unknown device 6622 (rev 01)) 2 Seagate ST380817AS, Rev: 3.42 (80 GB SATA) disks Disks each have 1 large partition with ext2 on them. 1. I boot off a Gentoo LiveCD running 2.6.9 2. I scp over some 180 MB simultaneously to the two disks across the network, one shell copying to 1 disk only 3. Unzip the .bz2 and .gz files just copied the files, again 1 shell working on each disk (no cross disk stuff going on at all). Typically, within a few minutes at most of the unzipping starting I get CRC errors on the files. No errors in dmesg necessarily. Sometimes I get errors unzipping - unmount the drive and run fsck which reports no errors - very insidious! I'd like the card to work - hey, I got one! and am willing to use my setup for testing of new driver versions. I'm useful with C, but not a kernel hacker, give me pointers to what needs done and I'll get it done, no worries... Let me know if I can help getting this thing fixed! Thanks, Johny A
