Hi Berck. I have more or less the same setup, abit kt7, duron, 2xibm30gb disks in raid0. And I used to have the same problems you have. At that moment (I don't know if something has changed recently, ask Arjan van de Ven) the problem was that the linux raid driver has to allocate memory to write to disk (buffers) but if you are out of memory, you first have write a bit to the cache, but the cache is located on the raid volume so the driver cannot write because it cannot allocate enough memory for buffers. DEADLOCK. What solved the problem for me was extra memory. I now have 1.5GB memory, and no more deadlocks. Other solutions might me disabling disk cache, put cache on other driver etc,etc. regards Bas Hulsken > From: "Berck E.
