There seem to be multiple issues mixed into one report. The initial report shows problems on generic write commands without any NCQ. The ICH6 controller used seems to use the same PCI ID for both piix and ahci modes (according to the Jaunty code). The second one fails on DMA read/writes with NCQ involved (so might have a controller in ahci mode).
@José, could you try to compare the behavior against the a recent mainline kernel https://wiki.ubuntu.com/KernelMainlineBuilds. Also, please supply "sudo lspci -vvvnnxxx" and the full dmesg from the boot. @Cedric, could you please open another bug report (with ubuntu-bug linux, so it gets automatic information attached). And if possible also compare the results with a recent mainline kernel. Maybe experiment with "libata.force=noncq" @ShinobiTeno, this is also a different controller. Have you tried to limit DMA speed with "libata.force=udma/66" to see whether this changes things? @Joachim, this definitely sounds like a different problem. Could you please open another report with "ubuntu-bug linux"? Thanks. -- ata timeout exception with ahci libata driver (was with 2.6.28-11, but i confirmed it affewcts previous kernels too) https://bugs.launchpad.net/bugs/352197 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
