This bug seems to be a duplicate of [Bug 38760] Re: ata timeout with sony vgn-s580 laptop
I don't know why but those SATA timeout messages occur less frequently for me if I add the ahci module to /etc/modules. Acer Aspire 9412WLMI Kubuntu Dapper with latest security updates. ii linux-image-2.6.15-26-686 2.6.15-26.46 ii linux-restricted-modules-686 2.6.15.24 ii nvidia-kernel-common 20051028+1 ii nvidia-glx 1.0.8762+2.6.15.11-3 I had to add the boot parameters "video=vga16fb:off video=vesafb:off" to prevent hard lockups due to bad interaction of nvidia and framebuffer drivers. Hibernation, neither suspend to disk, nor suspend to RAM, works for me at all. The laptop just freezes with a black screen. I tried KPowersafe and KLaptop with the same results. -- ata_piix problem with Intel ICH7 chipset https://launchpad.net/bugs/53754 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
