Description Flags
kernel config diff between vanilla 2.6.38 with working IDE controllers and FC15 default none

Description mark2 2011-05-26 22:07:51 UTC 
Description of problem:
New F15 install fails to recognize any IDE hard drives or CD rom drives

Version-Release number of selected component (if applicable):


How reproducible:


Expected results:

Kernel modules from a working linux distro which can work with the IDE drives from kernel 2.6.34

$ /sbin/lsmod | egrep -i '(ata|ide|scsi)'
sata_nv                18870  1
libata                157641  1 sata_nv
scsi_mod              165651  3 sg,sd_mod,libata
ide_cd_mod             23896  0
ide_generic             1091  0 [permanent]


Fedora kernel 2.6.38.6-27
$ /sbin/lsmod | egrep -i '(ata|ide|scsi)'
pata_mpiix              2284  0 
ata_generic             2647  0 
pata_acpi               2367  0 
pata_amd                7896  0 
sata_nv                16470  3 


Additional info:
Motherboard is Asus nForce4, using kernel param sata_nv.adma=0 has no effect.

Enabling kernel module amd74xx, ide_generic, and ide_cd_mod seems to have allowed the hdds to be accessed.

Note the usage counts for ide_cd_mod and ide_generic are both zero, meaning they are not being used at all. sata_nv is being used for the ata devices.

And here sata_nv is loaded and in use. Also ata_generic is the proper replacement for ide_generic and it is loaded. (Mixing the old ide and the new ata drivers is not a good idea.)

Please attach all the boot messages from the fedora kernel (as a plain-text attachment.)
