Dear all, two month ago, there was a patch submitted by the company areca regarding their in-kernel driver: "[PATCH v1.2 1/1] arcmsr: Support Areca new SATA Raid Adapter ARC1214/1224/1264/1284" This patch fixes (among other things) a major bug which forces a hardware reset on the adapter (1882 in our case, kernel log of error appended) and is leading to stability issues, but was rejected due to various reasons. The latest version of their patch works without error using the 3.10.17 longterm stable kernel, and with it our system seems to be running stable. Would it be possible to include this patch (or parts of it) into the linux kernel, so we won't have to worry about future incompatibilities with new kernel releases?
