 Posted: Tue Jan 13, 2009 3:54 am Post subject: [SOLVED] Laptop card reader makes 1st hard drive sdb |
 |
|
I'm getting a kernel panic at boot, the typical VFS error, can't mount root partition. Used to say something to the effect of "the following drives are recognized: <empty line>", now it recognizes only my primary partitions, not my linux partitions, (all inside the extended partition).
I've googled it and searched the forums, with no result. I figure it must be something simple in the .config, but I couldn't find anything. If it's not i'll chroot in and post my .config if necessary.
Thanks

How many harddrives do you have ?
Maybe the kernel is only seeing the drive you don't want, and is not seeing the drive with your root partition. |

it's a laptop. i have one hard drive. the kernel spits out that there's an sda, with size of like 1 and no partitions or something of the sort, an sdb with only sdb1,3,4 (sdb2 is extended, houses 5,6,7,8. ), and my dvd drive, sr0
EDIT: no smileys

Do you have the regular PC BIOS / DOS partition table, or did you go with something fancy like EFI / GUID partitions ?
This is what my kernel .config looks like.
| Code: | # grep -i partition .config
# Partition Types
CONFIG_PARTITION_ADVANCED=y
# CONFIG_ACORN_PARTITION is not set
# CONFIG_OSF_PARTITION is not set
# CONFIG_AMIGA_PARTITION is not set
# CONFIG_ATARI_PARTITION is not set
CONFIG_MAC_PARTITION=y
CONFIG_MSDOS_PARTITION=y
# CONFIG_MINIX_SUBPARTITION is not set
# CONFIG_SOLARIS_X86_PARTITION is not set
# CONFIG_LDM_PARTITION is not set
# CONFIG_SGI_PARTITION is not set
# CONFIG_ULTRIX_PARTITION is not set
# CONFIG_SUN_PARTITION is not set
# CONFIG_KARMA_PARTITION is not set
CONFIG_EFI_PARTITION=y
# CONFIG_SYSV68_PARTITION is not set |

Nope. MBR.
| Code: | CONFIG_PM_STD_PARTITION=""
# Partition Types
CONFIG_PARTITION_ADVANCED=y
# CONFIG_ACORN_PARTITION is not set
# CONFIG_OSF_PARTITION is not set
# CONFIG_AMIGA_PARTITION is not set
# CONFIG_ATARI_PARTITION is not set
CONFIG_MAC_PARTITION=y
CONFIG_MSDOS_PARTITION=y
CONFIG_MINIX_SUBPARTITION=y
CONFIG_SOLARIS_X86_PARTITION=y
CONFIG_LDM_PARTITION=y
# CONFIG_SGI_PARTITION is not set
# CONFIG_ULTRIX_PARTITION is not set
# CONFIG_SUN_PARTITION is not set
CONFIG_KARMA_PARTITION=y
CONFIG_EFI_PARTITION=y
CONFIG_SYSV68_PARTITION=y

this just seems to be some weird error.
I'm trying to see if I can find a boot log to post, but can't find one.

The output of this command might be helpful (from a LiveCD).

FcukThisGame,
Exact error messages will help.
Do you have a card reader in the laptop?
That may be detected as /dev/sda

| this usually means the kernel does not have support for the hard drive controller. boot cd, run lspci, who made the controller?. look at config for the missing support in device drivers. |

Sure was the card reader. Good call. My old laptop had one but it didn't cause my hard drive to be sdb.
Thanks, marking solved.
