Please post the full kernel log. FWIW, the 2.6.32-rc kernel has updates for the controller reset operations which may help get stubborn disks back on line. That patch is available for 2.6.28 to 2.6.31 kernels in the patch repository you mention below. > To solve my problem I patched the sata_promise-Module with your three > patches from "http://user.it.uu.se/~mikpe/linux/patches/2.6/OLD/2.6.24/"; > and installed the new module. > > After this I checked hopefully my /var/log/messages, but the disk run > anymore in 3.0GB/s-Mode, and again I become the I/O-problems: Incomplete messages. In particular, the limit-sataii-to-1.5Gbps patch has a printk() which is missing here. > Is there another possibility to force the Promise-Controller down to 1.5 > GB/s? Libata has a generic libata.force= parameter which can be used to tweak various settings, including 1.5Gbps vs 3Gbps. I haven't used it myself, but see Documentation/kernel-parameters.txt for details. /Mikael -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
