** Summary changed: - corruption when using md raid1 as root fs on amd64 smp + corruption when using md raid1 as root fs on amd64
** Description changed: Binary package hint: linux-image-2.6.15-28-amd64-server md5sum returns inconsistent results when run repeatedly on a large text file stored on a linux software (md) raid1 volume (ext3) which is the root filesystem. md5sum works fine when the raid1 is not the root fs, or when using a single standalone disk (also ext3). This is not the iommu issue experienced by other amd64 users: https://bugs.launchpad.net/ubuntu/+source/linux- source-2.6.15/+bug/128568 However, this system did experience the iommu issue and is currently running with iommu=soft as a workaround. This is happening on a dual dual-core opteron system with 8GB registered/ecc memory running up-to-date LTS. The system ran memtest86 for over 75 passes with no errors. I started a thread about this problem at http://ubuntuforums.org/showthread.php?p=3101571 , but another user suggested it was turning into a bug report.
