Linux 2.6.21.5 to 2.6.22.3: /dev/sda becomes /dev/hda

My system:
Toshiba Satellite A135-S4527
Slackware Linux 12.0

I'm currently using a custom build of kernel 2.6.21.5, under which my hard drive (correctly) appears as /dev/sda and my partitions appear as /dev/sda[1-6].

When I build a 2.6.22.3 kernel (using a slightly updated configuration), however, my hard drive becomes /dev/hda. When I manage to actually boot the system, reiserfsck warns that DMA is off on the hard drive. The system also suffers a severe slow-down.

What seems like the relevant section of the boot messages for the working kernel:

Is there some relevant configuration option that differs between the two kernel versions that could be responsible for this? I've revisited the configuration several times and tried rebuilding the kernel, but nothing seems to help. (I will gladly post any other information that may be helpful.)

Here's something I can spot a mile away?

Is there something wrong with 2.6.21.5 ?

What's this obsession with having the latest and greatest all the time?

When are you going to be a little bit settled with just a simple milestone?

Why not give 2.6.21.5 a chance to get it's bugs worked out before jumping onto the bandwagon of the Jone's Operating System + 1 ?

Don't you think it's bit of an obsession ?

Nobody can answer your question because that version of the kernel still has the paint drying on it.

2.6.21.5 was a major milestone, Slackware testifies to this.

Give it a break!

No problem here with kernel

Code:

slack@medino: ~ $ uname -r

My harddisk is plugged to a SATA-controller in a Medion Notebook. It is /dev/sda.

Here the output of dmesg:

P. S.: I can send you my /usr/src/linux/.config to check where the differences are.

That would be excellent!
It seems like that would be of immense help.:D

Your e-mail?

Fluxx.

I have this problem too.

I apologize too, ;-)

I would have sworn there is a rule against taking a discussion out the forum areas,
where they are public & can help everybody, into e-mail, where they aren't & don't.

Please do not use e-mail this way. If you think the files are too long or wide,
consider using a pastebin & posting the link here.

The main idea is that IDE must be entirely disabled. Disabling IDE caused my hard drive to function properly (and appear as sda) and my CD/DVD drive to function properly (I hadn't realized that this was misrepresented, too).

It is also a problem of Slackware's default kernel. I have two notebooks with SATA-controllers and DVD-burner.

Slackware's default kernels (2.6.21.5) use the harddisk as /dev/sda, what is correct and the DVD-burner as /dev/hdc, what causes immense problems. The DVD-drive is slow, dma cannot be enabled, burning is slow and needs 100 % CPU. During burning process there is no go for mouse or other usage of the system. This behaviour cannot be solved with the default kernel. Watching a DVD/VCD is horrible, there is a CPU-usage of 100 % (1,6 GHz Centrino, 1024 MB RAM) and the message, that the system is to slow to play DVDs!!! There are only some single pictures in a FPS of may be 10-12.

Only a recompiled kernel is able to use the DVD-burner in a correct way. To make this work I had to disable in /usr/src/linux/.config in section "Device Drivers" the subsection "ATA" completely.

Then the harddisk is /dev/sda (what is correct as before) and the DVD-burner is /dev/sr0 (what is correct then). No problems to use the DVD-burner, to watch DVD/VCD. The CPU usage is then 17 % with 600 MHz while watching a VideoDVD with mplayer.

I do not know the problem, but kernels of e. g. PCLinuxOS can handle the hardware of the notebook out of the box (/dev/sda and /dev/sr0).

P. S.: Sorry, I couldn't post the .config here, because 25000 signs are allowed and it had about 76000.
