** Changed in: linux (Ubuntu)
Sourcepackagename: None => linux
** Description changed:
i've very long time booting with Hardy 2.6.24-16
My config is: mobo Asus p5wdh video Asus en8500gt c2d 4500 2go ddr2 800
Kernel log report this line twice: Acpi exception (processor_core-0816):
ae_not_found processor device is not present [20070126]
I perform some search and have found discussions about this message: it seems
that appear when bios mobo have multi core capability and cpu used has only 1
or 2 cores.
example: my bios mobo is able to accept cpu with up to 4 cores, but i use a
core2duo on it. So the boot process try to find tthe 2 others missing core.
The result is a long time searching for that and report the acpi exception.
For better time booting, boot process might control the number of core
installed and not report the bios core capability.

a drive

information.
+ [ 31.127375] ata4.00: device is on DMA blacklist, disabling DMA
+ [ 31.127728] ata4.00: configured for PIO4
+
+ There are some additional messages regarding device sdd and this may be
+ the cause of the slow booting.
