 Posted: Sun Apr 30, 2006 5:55 am Post subject: [Solved]HP Pavilion Laptop and SATA |
 |
|
Hello all, this is my second time doing a gentoo installation, this time on a notebook instead of a pc and im running into a ton of problems.
I just got a HP pavilion dv5000t, it uses the intel chipset and an intel sata harddrive. I am using gentoo-sources-2.6.16-r3 and the Grub Boot Loader.
I selected the correct driver in my kernel (Intel PIIX/ICH SATA support).
When I booted from the livecd to do my install everything worked fine. However, when I try to boot my gentoo installation I get
| Code: | VFS: Cannot open root device "sda7" or unknown-block(0,0)
Please append a correct "root=" boot option
kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) |
I can go into my the Laptop's bios and "Disable Native Sata support" which allows my gentoo to boot perfectly. I'd like to run gentoo with the sata support, does anyone know if I can fix this? The Livecd works with Native sata support so there has to be something wrong. I've tried HP but they didnt know anything.
Heres my grub.conf
| Code: | timout 10
default 0
fallback 0
splashimage=(hd0,4)/grub/splash.xpm.gz
title Gentoo x86
root (hd0,4)
kernel (hd0,4)/boot/kernel-2.6.16-gentoo-r3 root=/dev/sda7

Try rebuilding your kernel after having changed in Bus Options -> PCI Access Mode ->(change from Any to Direct).
I think the mmconfig option is buggier than I thought.
That should allow you to boot in native mode.

Thanks for the suggestion. Tried setting it to Direct and it didnt work, also tried using the Bios setting and that failed too.
Any other ideas? |

The idea I gave you worked for an AMD64 mythtv box I was setting up for a friend so since it was in general the same error I thought it would be worth a shot for you. I will have a google around for you, but right now I suggest you unmask and emerge the mm-sources kernel patchset which will have a much more up to date libata and might give you a better chance of success.
Good Luck

I remeber another post I read about someone having a similar sata problem and they recommended opening the box up and disconnecting the card reader and usb and booting once. Really would rather not try that unless its totally necessary.
EDIT:
Solved this problem all I had to do was enable SATA AHCI support in the kernel, now I feel dumb lol. Anyway I think I finally got all of my machines hardware setup! |
