Primary channel reset. lost interrupt

[R Kimber]

Does anyone know what causes the following message, that I get
periodically.  No harm seems to have been done.  Everything seems
normal.

Smartmon tools and memtest don't show any problem with the hardware,
which is K8T Master2-FAR dual opteron, 2GB, with Maxtor disks.

Is it some sort of kernel/driver problem? I have 2.6.8.1-5-amd64-k8-smp.
