Problem Description:At bootup I end up in busybox and I see the following
message on the top of the screen "Gave up waiting for root device"
Actually I think that my hard drive "falls asleep" just after leaving grub.
When I'm in the busybox I need to unplug my hard drive (serial ata) and to plug
it again so that I can hear it restarting. After doing that I type exit in the
busybox and the boot process continues normally.
Dmesg shows me that:

[ 9.672007] ata3: link is slow to respond, please be patient (ready=0)
[ 14.320007] ata3: COMRESET failed (errno=-16)
[ 19.680006] ata3: link is slow to respond, please be patient (ready=0)
[ 24.328007] ata3: COMRESET failed (errno=-16)
[ 29.688007] ata3: link is slow to respond, please be patient (ready=0)
[ 59.092004] ata3: COMRESET failed (errno=-16)
[ 59.092004] ata3: limiting SATA link speed to 1.5 Gbps
[ 59.688009] ata3: SATA link down (SStatus 0 SControl 310)
[ 60.164017] ata4: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[ 60.196367] ata4.00: HPA detected: current 160834367, native 160836480
[ 60.196371] ata4.00: ATA-6: HDS722580VLSA80, V32OA6MA, max UDMA/100
[ 60.196373] ata4.00: 160834367 sectors, multi 16: LBA48

The COMRESET thing continues as far as I don't unplug and plug again my hard
drive.
I tried recently other distributions with the same kernel and I get the same
error (Debian and pmagic liveCD) So I think this bug concerns the kernel.
I also have to tell you that it's a SATA II hard drive (3gbps) on a (nforce 3)
SATA I controller (1.5gbps). And it appears that the controller does not fully
support the hard drive (or the SATA I retro-compatibility of the hard drive is
malfunctioning I don't know) But with older kernel it did always work without
any problem.

I'm running Ubuntu intrepid ibex alpha up-to-date, kernel 2.6.27-1.2 (I
recently updated from 2.6.26 to 2.6.27 but the problem is the same)

Thanks

I don't know how to attach files here so if you want the dmesg.log etc. files I
reported the bug on launchpad where you'll find these files.
