Hi!

I'm writing for you because i'm experiencing some serious problems with the
IDE system on linux kernel 2.6.22 series, *I think* specifically with the
module IDE_GENERIC.

This is tested on all the 2.6.22 kernels (2.6.22, 2.6.22.1, 2.6.22.2, 2.6.22.3
and 2.6.22.4).

Well, I'm using Debian GNU/Linux on a Lenovo 3000-n100 laptop. The kernel that
I'm using now is a 2.6.20.15, compiled by myself, which works correctly. But
when I try to run a 2.6.22 series kernel, compiled with the same options than
the 2.6.20.15, some bad things happens.

First, there is a kernel panic, because kernel tries to boot the root
partition from a hda disk, but I'm using sda disks, not hda.

Here is the kernel panic message:
###################
#VFS: Cannot open root device "sda3" or unknown-block (0,0)
#Please, append a correct "root=" boot option; here are the available
#partitions:
#0300 97685784 hda driver: ide-disk
# 0301 29832763 hda1
# 0302 4931955 hda2
# 0303 60308010 hda3
# 0304 1 hda4
# 0305 2610531 hda5
#Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block
#(0,0)
###################

Somebody tolds me that I can solve this problem unchecking the IDE_GENERIC
option in the kernel configuration. It's true, but when I do this the DVD
device is not recognized by the kernel. No exists. In my working 2.6.20.15
kernel, the 'cat /proc/ide/drivers' command outputs this:
###################
#ide-disk version 1.18
#ide-cdrom version 4.61
###################

But in 2.6.22.X, the output is only:
###################
#ide-disk version 1.18
###################

I'm sure that is not a bad configuration options problem, because the problem
appears too when, for example, I try to boot an openSUSE-10.3-beta liveCD,
which has a 2.6.22.1 kernel, and boot process stops with this warning:
###################
#----> Probing module: generic
#----> Failed to detect CD drive!
#----> rebootException: reboot in 60 sec...
###################

Well, I never reported a kernel bug and I'm following the submitting
recomendations of the webpage:
http://www.eu.kernel.org/pub/linux/docs/lkml/reporting-bugs.html
So, there is some information about my system for your consideration:
