Dear all,

(please Cc)

since going from 3.2 to 3.3-rc1 I see a kind of regression wrt booting
time, namely the detection of the CD drive hangs for 10sec (both
dmesg were taken on the same hardware on the same day):

with 3.3-rc1 and rc2:
[    3.694012] sd 0:0:0:0: [sda] Attached SCSI disk
[    9.004013] ata2: link is slow to respond, please be patient (ready=0)
[   13.652013] ata2: COMRESET failed (errno=-16)
[   13.972022] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300)

I'm looking into this problem.
But I can't reproduce this regression.

Could you attach the full 3.3-rc2 dmesg?

And could you do a bisect?

First, you can check if commit 318893e is good or bad.

If it's bad, then you only need to do a bisect between v3.2 and 318893e.
Otherwise, you need to do a bisect between v3.2 and v3.3-rc1.

Thanks,
