Comment 118 for bug 346691

The issue is on 64bit kernels 2.6.29-02062904-generic AND kernel 2.6.28-11-server.

I believe I'm seeing the same issue on ICH10 AND SiI 3132 ... separate software raid (raid1 and raid5) on both controllers are suffering. Everything was OK until a couple of days ago, issue only came up when I started playing with larger files. Issue manifests itself on XFS, ext4, and directly on software raid device, and directly against disk.

I've run memtest 6+ passes with no errors, in addition to badblocks on each disk and the combined arrays. No SMART issues on the disks.

My test is basically creating files (11 gigs in size) with /dev/random and dd, and then reading back X bytes with md5sum.
