Long wait for harddisk detection during kernel boot

[Rob Lahaye]

Hi,

I'm using 4.7 Release.

When the kernel boots, I get a relatively long wait (a minute or more)
at the harddisk detection. The HD is a IBM-DTLA/30.7Gb; CPU is Intel
1.7 GHz.

For the whole 'dmesg' output, see below in the PS; the place where the
wait occurs is here:

[...]
   atapci0: <Intel ICH2 ATA100 controller> port 0xb800-0xb80f at device 31.1 on pci0
   ata0: at 0x1f0 irq 14 on atapci0
[ HERE is the long wait!  ]
   ata1: at 0x170 irq 15 on atapci0
   uhci0: <Intel 82801BA/BAM (ICH2) USB controller USB-A> port 0xb400-0xb41f irq 11 at device 31.2 on pci0
[...]

Any ideas why the kernel boot is not going smooth at that point?

Thanks!

Rob.
