** Tags removed: needs-upstream-testing ** Description changed:
System info: Hardware: Mainboard MSI 965P Neo2, Intel 965 chipset, ICH8 southbridge, chipset 82801H, One SATA Samsung Harddisk 300GB, One SATA optical drive, both connected to the chipset's SATA channels 3 and 4 (behaviour is unchanged if connected to channels 1 and 2). SATA is running in IDE mode, AHCI mode is not supported by the hardware. Software: - Affects kernel version 2.6.27-7-generic, Ubuntu 8.10 - Doesn't affect kernel version 2.6.24-19-generic, Ubuntu 8.04 or ubuntu 8.10, or earlier versions + Affects all kernel versions from version 2.6.26 to 2.6.28-13-generic and (untested) maybe later versions also + Doesn't affect kernel version 2.6.24-19-generic, Ubuntu 8.04 or ubuntu 8.10, vanilla 2.6.25, or earlier versions Symptoms: Booting ubuntu 8.10 with the included kernel 2.6.27-7-generic from either the live CD or as a system on disk upgraded via apt-get dist-upgrade stops at the point where the root partition is to be mounted. The BusyBox initramfs shell prompt appears after a timeout period, and when listing the "/dev" directory I can see that it doesn't contain any disk related device nodes, even the "dev/disk" directory is missing. The output of dmesg is showing that all four SATA channels are correctly recognised and initialised, but they all show a message "SATA link down", just as if no disk was connected to them. There are no further SATA/ATA related error messages in the dmesg output. Reproducibility: Booting the same system with a still-installed 2.6.24-19 from Ubuntu 8.04 works without any problems. The dmesg output is mostly the same as with 2.6.27, the only notable difference is that instead of the message "ata3: SATA link down" and "ata4: SATA link down" it now show the correct initialisation messages for my drives in the same place in the dmesg output. Manually trying to load the sd_mod module from the initramfs prompt didn't bring the missing device nodes into existence either. Connecting a USB flash memory storage device and mounting it in the BusyBox initramfs shell works, however (in which case the necessary USB-disk-related device node is created automatically under /dev), and this way I was able to capture the dmesg output and attach it below. The attached files are: 1: The output of lspci to further specify my hardware configuration 2: The output of dmesg from the initramfs shell of kernel 2.6.27 3: As a comparison the output of dmesg from the working kernel 2.6.24 setup ** Description changed: System info: Hardware: Mainboard MSI 965P Neo2, Intel 965 chipset, ICH8 southbridge, chipset 82801H, One SATA Samsung Harddisk 300GB, One SATA optical drive, both connected to the chipset's SATA channels 3 and 4 (behaviour is unchanged if connected to channels 1 and 2).
