[Bug 595448] Re: Slow boot caused by SATA controller reset

[Jarrett Miller]

Its a SATA DVD-RW drive so suggestions 1 and 2 don't make any sense.

As for number 3,  I stated in my first post the motherboard BIOS is the
latest available. The DVD drive firmware is also the most recent
available.

As for 4&5, they are not applicable. The boot delay I submitted this bug
before occurs well before the initramfs is expanded let alone the root
file system mounted. So they just don't apply at all. Let me be very
clear here. This pause in boot up occurs very early during kernel
initialization before the initramfs is utilized. For example if I boot
with a GRUB configuration line that has no initramfs specified the boot
delay is still present. Of course the system fails to boot if I do this
but I did try it out just to be sure it was not an initramfs issue which
is why I submitted the bug against the kernel and not some component of
the initramfs bootup system.

I am not sure what in general you want me to check for a workaround. As
I previously posted I have already provided a solution.

The karmic kernel .config file had CONFIG_SATA_AHCI=y specified while
lucid specifies CONFIG_SATA_AHCI=m. this is the problem. It is a simple
regression from karmic and is why I added the bitesize tag per the
instructions on the wiki.
