HA! Fixed this problem. As per above I was running ubuntu hardy with kernel 2.6.24-23. Upgrading to the latest Intrepid stable kernel solved this problem for me!
Here's what I did: Add the Intrepid repository temporarily by appending the following to /etc/apt/sources.list: {{{ # Temporary Repositories to pull new Intrepid kernel deb http://ca2.archive.ubuntu.com/ubuntu intrepid main restricted deb-src http://ca2.archive.ubuntu.com/ubuntu intrepid main restricted }}} Update the repo cache: {{{ sudo apt-get update }}} Determined what the latest repository was: {{{ sudo aptitude search linux-headers-* }}} Learned it to be 2.6.27-7! ... so install it! {{{ sudo apt-get install linux-backports-modules-2.6.27-7-generic linux-headers-2.6.27-7 linux-headers-2.6.27-7-generic linux-image-2.6.27-7-generic linux-restricted-modules-2.6.27-7-generic linux-source-2.6.27 linux-doc-2.6.27 }}} (notice I went overboard on WHAT to install ... because frankly I didn't know what I did and did not require ...) After a few minutes, the kernel was installed, and headers updated in /boot/grub/menu.lst. Restarted the server first (to make sure nothing blew up...). Everything looked fine, so I shutdown the server. Installed a SATA drive to the 82801JI (ICH10 Family) SATA AHCI Controller. Here's an output (filtered) of "sudo lspci -C Storage": {{{ *-storage description: SATA controller product: 82801JI (ICH10 Family) SATA AHCI Controller vendor: Intel Corporation physical id: 1f.2 bus info: p...@0000:00:1f.2 logical name: scsi3 version: 00 width: 32 bits clock: 66MHz capabilities: storage msi pm ahci_1.0 bus_master cap_list emulated configuration: driver=ahci latency=0 module=ahci }}} No more errors! Looks like at some point in the kernel this issue was fixed. Simply upgrade to a later distro, or upgrade your kernel, and you should be fine. PS: Don't forget to remove the temporary repo entries in /etc/apt/sources.list and follow with an apt-get update. -- Jmicron AHCI controller probs... https://bugs.launchpad.net/bugs/198871 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
