Message-ID: <20070610185439.GA12202@alinoe.com> Mail-Followup-To: Carlo Wood , linux-kernel@vger.kernel.org MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.5.13 (2006-08-11) Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1698 Lines: 51 I've been trying for months to get my box to boot faster by ignoring the not connected hda/hdb (ide0). ansset:~>dmesg | egrep '(noprobe|ide0|hda|hdb)' Kernel command line: root=/dev/hde3 ro ide0=noprobe ide0: BM-DMA at 0xd800-0xd807, BIOS settings: hda:pio, hdb:pio Probing IDE interface ide0... hda: IRQ probe failed (0xfffffdb8) etc. or Kernel command line: root=/dev/hde3 ro hda=none hdb=none ide0: BM-DMA at 0xd800-0xd807, BIOS settings: hda:pio, hdb:pio Probing IDE interface ide0... hda: IRQ probe failed (0xfffffdb8) same for hda=noprobe hdb=noprobe Nothing helps. Is this a bug or not? I'd think that saying "noprobe" means "do NOT probe" - but it probes anyway. The documentation also tells me that =none should CERTAINLY make it ignore the non-existant drives - but it keeps probing. Shouldn't an explicitely added kernel parameter be taken a little bit more serious by the kernel? Independent on whether or not a drive is detected (or what the CMOS might think about that), I think that the kernel should REALLY, totally ignore an ide and/or hdX if so explicitely requested with a kernel parameter. Anything I missed? -- Carlo Wood PS Sorry if this is a FAQ (it seems so) -- I just can't find a satisfactory answer anywhere as to why explicit parameters like this are ignored and want to ask to change this. Or, I cannnot find the solution for this problem and get my damn ide0 NOT probed. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
