Kernel Rebuild Nightmare

squirellplaying · 01-19-2005, 07:33 PM

I'm trying to rebuild the kernel for 2.6.10 on debian sarge. I managed to configure the kernel to what I think my needs are and install it I suppose using dpkg. I used this guide with a few mods. The grub config file for the new kernal is:

Code:

root (hd0,0)
kernel /vmlinuz-2.6.10-20040119 root=/dev/hda4 ro
savedefault
boot

But when it boots I get the following errors:

Code:

VFS: Cannot open root device "hda4" 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)

In my kernel I was sure to build in, not as modules, EXT2, EXT3, INITRD, and ramfs support, since those are the file types I'm using. Am I missing something stupid?

Partion table:

Code:

1 - boot         [ext2]
2 - swap        [ext3]
3 - unknown  [extended]
4 - root          [ext2]
5 - home        [ext2]

you probably didn't include the IDE driver into your kernel when building (or included IDE as a module - to be loaded from ... IDE :-)

you will also need EXT2 compiled in for the same reasons.

As far as I can tell the IDE driver is included in my kernel.

Code:

# ATA/ATAPI/MFM/RLL support
#
CONFIG_IDE=m
CONFIG_BLK_DEV_IDE=m

#
# Please see Documentation/ide.txt for help/info on IDE drives
#
# CONFIG_BLK_DEV_IDE_SATA is not set
CONFIG_BLK_DEV_HD_IDE=y
CONFIG_BLK_DEV_IDEDISK=y
# CONFIG_IDEDISK_MULTI_MODE is not set
CONFIG_BLK_DEV_IDECD=m
CONFIG_BLK_DEV_IDEFLOPPY=m
# CONFIG_BLK_DEV_IDESCSI is not set
# CONFIG_IDE_TASK_IOCTL is not set


# IDE chipset support/bugfixes
#
CONFIG_IDE_GENERIC=m
# CONFIG_BLK_DEV_CMD640 is not set
# CONFIG_BLK_DEV_IDEPNP is not set
CONFIG_BLK_DEV_IDEPCI=y
# CONFIG_IDEPCI_SHARE_IRQ is not set
# CONFIG_BLK_DEV_OFFBOARD is not set
CONFIG_BLK_DEV_GENERIC=m
# CONFIG_BLK_DEV_RZ1000 is not set
CONFIG_BLK_DEV_IDEDMA_PCI=y
# CONFIG_BLK_DEV_IDEDMA_FORCED is not set
CONFIG_IDEDMA_PCI_AUTO=y
.
.
.
CONFIG_BLK_DEV_VIA82CXXX=m
# CONFIG_IDE_ARM is not set
CONFIG_BLK_DEV_IDEDMA=y
# CONFIG_IDEDMA_IVB is not set
CONFIG_IDEDMA_AUTO=y

From what I can tell it uses the VIA driver. LSPCI out put:
