[Cbe-oss-dev] Need for explanation about the dmabench bug

[Nathalie Casati]

Hi,

I've been playing with the dmabench app included in the SDK. After a
short while I discovered that launching it on 5 SPEs causes the Cell (in
my case a playstation3) to freeze completely.

I found this post :
http://www.ibm.com/developerworks/forums/message.jspa?messageID=13985391
regarding the subject. It is not very precise about the cause of this
problem, nor the solution.
I'm running gentoo with a patched 2.6.23 kernel (ps3-sources included in
the cell overlay).

Has anyone an explanation about this issue, a solution and or any other
idea ?

Thank you, Nathalie Casati
