This patch seems to work fine. So we should teach Atto to submit this patch to the Linux kernel instead of trying to roll their on driver? Or can this be implemented without asking Atto? Atto seems to prefer their own driver, they say on their web site: Linux Support for ExpressPCI. ATTO strongly recommends using the RedHat/SUSE driver for all installations. Linux support was previously provided for the 2.4 and 2.6 kernels via patches to the LSI Logic Fusion MPT driver. However, these patches are no longer supported. Release notes and installation instructions are included in the download packages. Red Hat/SUSE Linux driver v1.00 (File Size393KB) This driver is recommended for use with the Red Hat Linux Enterprise 3.x/4 and SUSE Linux Enterprise Server for x86, x64(AMD64, EM64T), and IA-64 (Itanium) systems. The following patches are available for those who prefer the older driver: Linux 2.4 Driver Patch for LSI Logic Fusion-MPT Driver v2.05.00 (File Size 2.2KB) The LSI Logic Fusion-MPT Driver v2.05.00 can be downloaded here (File Size 23.4MB). Linux 2.6 Driver Patch for LSI Logic Fusion-MPT Driver (File Size 2.1KB)The LSI Logic Fusion-MPT Driver v3.01.xx is included with the Linux kernel. > Apparently ATTO devices have a completely different NVRAM format - > maybe this causes the problem when a driver with just a PCI ID added > tries to interpret NVRAM data using the LSI format? This explains the problem. It is even surprising that it worked at all...
