[Bug 44017] ACPI - libata IDE regression 2.6.15-20 => 2.6.15-21

[Michal Pokrywka]

Public bug reported:

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
Binary package hint: linux-source-2.6.15

Dapper flight 6 started on my notebook (Asus W3V) without problems.
Recently I downloaded kubuntu flight 7 and somehow managed to
install it on hdd - live cd paused on initrd, but resumed after a minute or two.
I installed kubuntu but system failed to boot after restart.
Flight 7 boots with acpi=off kernel parameter, I also copied
kernel from Flight 6 (2.6.15-20-386) and it boots without problems.
Dmesg, lspci, dmidecode attached.
Thanks to featurefull initrd I managed to save "dmesg" from
failed boot to pendrive - also attached.
