 Posted: Sun Mar 30, 2003 12:49 pm Post subject: Kernel command line ignored |
 |
|
I have a strange problem with a kernel build from gentoo-sources-2.4.20-r2 -- it ignores my kernel command line.
I added
| Code: | | append = "ide2=ata66 hdc=ide-scsi" |
to my lilo.conf. SCSI emulation for my CD-Writer and UDMA for my Promise Ultra 100.
With vanilla-souces-2.4.20 everything works the way it should.
dmesg output:
| Code: | Kernel command line: BOOT_IMAGE=Linux_old ro root=2105 ide2=ata66 hdc=ide-scsi
ide_setup: ide2=ata66
ide_setup: hdc=ide-scsi
Initializing CPU#0
<snip>
PDC20268: chipset revision 2
PDC20268: not 100% native mode: will probe irqs later
PDC20268: (U)DMA Burst Bit ENABLED Primary MASTER Mode Secondary MASTER Mode.
PDC20268: ATA-66/100 forced bit set (WARNING)!!
ide2: BM-DMA at 0x6400-0x6407, BIOS settings: hde:pio, hdf:pio
ide3: BM-DMA at 0x6408-0x640f, BIOS settings: hdg:pio, hdh:pio
|
SCSI emulation is also setup properly.
Now with gentoo-sources:
| Code: | Kernel command line: BOOT_IMAGE=Linux ro root=2105 ide2=ata66 hdc=ide-scsi
Initializing CPU#0
<snip>
PDC20268: chipset revision 2
PDC20268: not 100% native mode: will probe irqs later
PDC20268: (U)DMA Burst Bit ENABLED Primary MASTER Mode Secondary MASTER Mode.
ide2: BM-DMA at 0x6400-0x6407, BIOS settings: hde:pio, hdf:pio
ide3: BM-DMA at 0x6408-0x640f, BIOS settings: hdg:pio, hdh:pio
|
Note that the lines
| Code: | ide_setup: ide2=ata66
ide_setup: hdc=ide-scsi |
are missing here.
With gentoo-sources I don't get my CD-Writer to work and UDMA100 doesn't work, either.
The two kernels are configured in the exact same way regarding SCSI emulation and Promise chip support.
What's wrong with my gentoo-sources kernel? |

Sorry, I do not have any solution for this problem. I just wanted to let you know that I am experiencing exactly the same problem. The kernel options are in my case:
| Quote: | | ide2=ata66 ide3=ata66 |
They seem to be ignored, as I also don't get the ide-setup message. I am using a pdc202xx Ultra DMA 100 controller with two IBM UDMA 100 harddisks attached to it. They just run at UDMA 33 because the kernel options are somehow ignored. I have also found out that with the stock vanilla kernel 2.4.20 from www.kernel.org works fine with these kernel options and the disks are running with full speed at UDMA 100. So I am assuming the gentoo-patches cause the "problem", but I did not have the time till now to investigate any further. If I find a solution, I will let you know. I think it is also worth opening a bug report for this.

| I am also having this problem. With gentoo-sources (I have tried 2.4.20-r2 and 2.4.20-r3) I add hdc=ide-scsi to the kernel like in grub.conf and SCSI emulation does not get turned on. I use vanilla sources (2.4.20) and the same grub.conf, SCSI emulation works. How are you all getting these kernel command lines working with gentoo-sources? |

| The new syntax is hdx=scsi |

| Well that doesn't work either. And I should add that it is not just the SCSI emulation parameter, the "video=vesa:..." doesn't work either. I just tested gaming-sources, gs-sources, and ck-sources. The gaming-sources, gs-sources, and gentoo-sources are all packaged and distributed by Gentoo. None of the Gentoo managed ones work. ck-sources, one not managed by Gentoo does work fine. Isn't that weird? |

Exactly, it's not just the scsi emulation, but other options, too.
However my bugreport has been marked as a dublicate of this scsi centric bug  |
