I updated the bug desc and title to reflect new findings. The issue is definitely located in the AHCI driver, as per my previous comments, and it affects all kernels tested (2.6.27-* and 2.6.28-* on intrepid, jaunty beta, jaunty release and debian lenny up to now).
The workaround i used works for 2.6.27 kernels, as ahci is loaded as a module and can be blacklisted in /etc/modprobe.d/blacklist. Unfortunately, 2.6.28 kernels in ubuntu (haven't tested with debian again) do not load ahci (or any libata driver, for that matter) as modules, but are now built-in into the kernel, so my workaround is useless. Any help on how to disable ahci when it's built in (ie, force the kernel to use ata_piix anyway) would be greatly appreciated. note that i do not have any intention of recompiling the kernel :) If you need more information, please let me know. -- 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
