Bug Description
Binary package hint: linux-image-
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:/
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://
System specs:
Tyan Transport B2891G24S4H
Motherboard: Thunder K8SRE S2891 (nForce Professional 2200)
8x1GB of Corsair CM72SD1024RLP-
Disks: root fs on two WD3200RE using linux raid1, SATA
