Originally reported here : https://bugs.launchpad.net/ubuntu/+source/linux/+bug/427362 You can found in this bugs some logs (lspci/dmesg...) I must set SATA to IDE in BIOS (removing AHCI) because kernel hang and output errors DRDY
If you need more specifics informations, tell me. This notebook is the same as Acer Timeline 1810, it's a PACKARD BELL DOT M/U.FR-020
A workaround is to add : acpi=off in kernel boot parameters This bug is confirmed also on an Acer Travelmate 8371 I'v found may be same bug on others distros : https://qa.mandriva.com/show_bug.cgi?id=49818 https://bugzilla.novell.com/show_bug.cgi?id=443143
Let's concentrate on your machine for now. It sounds like IRQ routing problem w/ acpi. Can you capture the failing boot log w/ ahci and w/o acpi=off? You'll either need to boot into rootfs on a different device or use net or serial console to capture kernel messages. (cc'ing Thomas for acpi / IRQ stuff)
Using this tutorial : https://wiki.ubuntu.com/KernelTeam/Netconsole#Netcat%20(Linux) I can have informations on boot with SATA=IDE (see attachment), but with SATA=AHCI I have no output on my netconsole

Ummm... netconsole seems to have been initialized pretty late during boot. To do it properly, you'll need to build in the network driver and netconsole support into the kernel instead of as modules and enable it with kernel boot parameter. Please read Documentation/networking/netconsole.txt.
Can you attach acpidump, please. The tool should also work if booted with acpi=off Not sure how easy this is with Ubuntu, with SUSE it is possible to start the installation with some linuxrc options and activate ssh. Then you can log in on the affected machine, even if the disk is not accessable, get /proc/interrupts, dmesg, lspci -vv -n, etc. and you can copy it away via scp. You could also try to reproduce this downloading latest 11.2 OpenSUSE mini iso which should also be 2.6.31 based and install with parameters SSHPassword=12345678 usessh=1 (cmp. with http://de.opensuse.org/Linuxrc). The network install iso should be enough and only has about 100M: http://software.opensuse.org/developer or http://download.opensuse.org/distribution/11.2-Milestone7/iso

Thanks for all yours instructions, I will try to do them this week-end, and thanks for your patience :)
