Bug Description
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_
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.
Found in dmesg:
[ 31.127369] ata4.00: Drive reports diagnostics failure. This may indicate a drive
[ 31.127372] ata4.00: fault or invalid emulation. Contact drive vendor for 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.
