Bug 156909 – gentoo-sources-2.6.19-r1 does not detect sda partitions

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Frank Russo 2006-12-02 06:54:22 UTC]

Good afternoon,

sys-kernel/gentoo-sources-2.6.19-r1 does not appear to detect the single ext3 partition on /dev/sda (/dev/sda1)

h2so4 dev # fdisk -l /dev/sda
h2so4 dev # uname -a
Linux h2so4 2.6.19-gentoo-r1 #1 SMP Sat Dec 2 14:26:10 Local time zone must be set--see zic m x86_64 Intel(R) Pentium(R) D  CPU 2.66GHz GenuineIntel GNU/Linux

The problem does not appear with linux-2.6.18-gentoo-r3.  I am certain that ext3 is compiled into the kernel (as my / partition on hda is ext3).  In the 2.6.19 logs I see the following. 

Dec  2 15:34:21 h2so4 sd 0:0:0:0: Attached scsi removable disk sda

With 2.6.18
Dec  2 15:20:54 h2so4 sd 0:0:0:0: Attached scsi disk sda
Dec  2 15:20:54 h2so4 SCSI device sda: 586072368 512-byte hdwr sectors (300069 M
B)
Dec  2 15:20:54 h2so4 sda: Write Protect is off
Dec  2 15:20:54 h2so4 sda: Mode Sense: 00 3a 00 00
Dec  2 15:20:54 h2so4 SCSI device sda: drive cache: write back
Dec  2 15:20:54 h2so4 SCSI device sda: 586072368 512-byte hdwr sectors (300069 M

Dec  2 15:20:54 h2so4 sda: Write Protect is off
Dec  2 15:20:54 h2so4 sda: Mode Sense: 00 3a 00 00
Dec  2 15:20:54 h2so4 SCSI device sda: drive cache: write back
Dec  2 15:20:54 h2so4 sda: sda1
Dec  2 15:20:54 h2so4 sd 0:0:0:0: Attached scsi disk sda

The biggest difference that I see is that with 2.6.18, it is detected as a "scsi disk" and with 2.6.19 it is detected as a "scsi removable disk".

SATA has changed name. CONFIG_ATA and CONFIG_ATA_your_sata_controller are disabled in your config. That's your problem.

[Comment 9 Frank Russo 2006-12-02 07:35:13 UTC]

Ahh,  So...

< CONFIG_ATA=y
< CONFIG_ATA_PIIX=y
< CONFIG_SATA_INTEL_COMBINED=y
< CONFIG_PATA_IT821X=y
< CONFIG_PATA_MPIIX=y

This resolved the problem.  Would you consider this a "genkernel" bug?

Thank you for your time,
Frank Russo

Closing. Don't recycle .config files between different kernel versions.
