K7 kernel cannot find /dev/hda1

[Martijn Vermaat]

After upgrading from Breezy to Dapper today, the new kernel could not boot my system. In recovery mode, the last lines are:

---------

[...] hda: Maxtor 6Y120p0, ATA DISK drive
[...] hdb: WDC AC28400R, ATA DISK drive
[...] hdc: ASUS CRW-5232AS, ATAPI CD/DVD-ROM drive
[...] ide0 at 0x1f0-0x1f7, 0x3f6 on irq 14
[...] ide1 at 0x170-0x177, 0x376 on irq 14
Done.
Mounting root file system... ...
Running /scripts/local-top ...
Done.
ALERT! /dev/hda1 does not exist. Dropping to a shell

---------

This is 2.6.15-18-k7 on an ASUS NForce2 Athlon system. The 386 version of the same kernel boots fine, and so do 2.6.12-x-k7 and 2.6.10-x-k7 kernels. Oh, /dev/hda1 is an ext3 filesystem.

In another bug report the ide=reverse option was suggested by Ben Collins, but it didn't make any difference.

Can you try a "dpkg-reconfigure linux-image-2.6.15-18-k7"
once you have booted into the -386 kernel?

[Martijn Vermaat (mvermaat)]

That did the trick. After reconfiguring the k7 package I can boot with that kernel.

A friend just had the same issue on upgrade, why is running the dpkg-reconfigure required? What does it change on reconfigure?

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this linux-source-2.6.15 kernel bug to the new "linux" package. We appreciate your patience and understanding as we make this transition. Also, if you would be interested in testing the upcoming Intrepid Ibex 8.10 release, it is available at http://www.ubuntu.com/testing . Please let us know your results. Thanks!
