ACPI_SDD failed - boots slowly

[arno]

Binary package hint: acpi

My Acer Timeline 8571 takes quit a bit longer to boot as it should be. I am not sure wich packet is responsiple. Is this a driver issue?
What can I do?
My suspect is, that this has to deal with my other bug (does not resume from hibernate - makes reboot instead).
I can swithoff acpi as kernel parameter, but this has a lot of bad side effects...

This is a kernel annoyment. I'm not sure if it is fixed in later versions (do you use a kernel from the proposed repository?), you can however work around this bug with the following kernel command line option: libata.noacpi=1
Add that to the GRUB_CMDLINE_LINUX_DEFAULT variable in /etc/default/grub (GRUB2 only, I assume you're using 9.10) and you should be set.

This is fixed in Lucid btw. At least for me.
