Subject: AHCI driver prints "D2H reg with I during NCQ" message, what is it?
Date: Fri, 13 Jul 2007 11:28:58 -0400 [thread overview]
Message-ID: <46979A3A.2090005@redhat.com> (raw)
I see this on boot with kernels 2.6.22.1 and 2.6.20.15:
ata1: D2H reg with I during NCQ, this message won't be printed again
But I can't find anything that tells me what it means, or whether
it's a real problem.
x86_64 kernel with controller:
00:1f.2 SATA controller: Intel Corporation 631xESB/632xESB SATA Storage Controller AHCI (rev 09)
and drive:
ata1.00: ATA-7: HDS728080PLA380, PF2OA63A, max UDMA/133
