[dm-devel] Errors using RDAC

[S. J. van Harmelen]

Hi all,

I get these errors in my log and I just had an interuption in our
production traffic:

Could anyone tell me what is wrong? I didn't had these errors when using
RDAC without the hardwarehandler en with kernel 2.6.22.2

Hope someone can help me with this and tell me how serious this is!
