Where is SCSI info?

Right there, under the text (It was so short, that I thought to put it in the message. Maybe I should have put that also in pastebin for consistency and clarity):

Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: ATA      Model: KINGSTON SVP200S Rev: C4
Type:   Direct-Access                    ANSI  SCSI revision: 05
Host: scsi1 Channel: 00 Id: 00 Lun: 00
Vendor: hp       Model: CDDVDW TS-L633M  Rev: 0301
Type:   CD-ROM                           ANSI  SCSI revision: 05

I think networking changes shouldn't cause this ACPI regression, right?

Yeah, beats me, but that's what I got by bisecting. My expertise ends about here.
