** Summary changed:
- opteron amd64 data corruption
+ corruption when using md raid1 on amd64 smp
** 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.
+ file stored on a linux software (md) raid1 volume (ext3). md5sum works
+ fine when using a single standalone disk (also ext3).
This is not the iommu issue experienced by other amd64 users:
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. Some more background info
is available there.
