[Bug 186574] [NEW] divide error in 2.6.20-15-server-amd64

[Øyvind Repvik]

Public bug reported:

Binary package hint: linux-image-server

I am getting a reproducible "divide error" on kernel 2.6.20-15 on feisty. 
I'm running on an AMD64 x2, 6gb ram. Using LVM2, one striped LV and a few non-striped LVs. 
If any more info is needed, please ask.
