Thanks a lot, it helped.

Remove 
Device Drivers ->
ATA/ATAPI/MFM/RLL support ->
generic/default IDE chipset support

and 

Device Drivers ->
Serial ATA (prod) and Parallel ATA (experimental) drivers ->
Generic ATA support

from your Kernel config. You might be using generic drivers instead of
your specific drivers. Also double check all kernel options concerning
Disk controllers.

[gentoo-user] disk problem after kernel update

2007-12-09 Thread pat 
Hello,

I've try to update kernel from 2.6.20-gentoo-r8 to 2.6.23-gentoo-r3. I've copied
config, run make oldconfig and then make.

At boot time the new kernel maps disks as hdax, but previous kernel mapped disks
as sdax. So, if I want to use new kernel I have to change fstab (that's not so
bad), but I have to setup DMA for the disk, and that's not possible (an error 
occur)

Did I something wrong? How to solve it?

The GRUB boot options:

*** new one
title GNU/Linux 2.6.23-gentoo-r3
root (hd0,2)
kernel /boot/kernel-2.6.23-gentoo-r3 real_root=/dev/hda5 atapi_enabled=1
hdc=noprobe nmi_watchdog=0 root=/dev/hda5


*** old one
title GNU/Linux 2.6.20-gentoo-r8
root (hd0,2)
kernel /boot/kernel-2.6.20-gentoo-r8 real_root=/dev/sda5 atapi_enabled=1
hdc=noprobe nmi_watchdog=0


Thanks a lot.
