After upgrading firmware to 3.10 or 3.12 any disk operations causing 100% cpu load and disk corruption, for now I have 0.9% of badblocks. When trying upload files via ftp ,for example, it uploading with low speed around 5-10 Kbps and cpu loads to 100%. Last working fw was 3.08.Also I cannot find 3.08 at i.mt.lv/routerboard/files/ - only buggy 3.10 and 3.12 available.
