 Posted: Tue Jun 08, 2010 8:53 am Post subject: Wrong sequence of dev.numbering on kernel w/o initrd[solved] |
 |
|
Hi Geeks,
please give me some hints to find out whats wrong here.
I've just build my own kernel by hand, first time based on Pappys kernel seeds, and first time on these machine (not first time at all).
Before that i used genkernel on that machine, wich i edit by hand in the kernel.config, to make it more lean, for lots ok kernel generations.
The last genkernel i used was 2.6.33-gentoo-r2, the new kernel without initrd i may speek about now, is 2.6.34 (both from gentoo-sources)
The curious thing is: when booting the new 2.6.34 kernel, my first an only sata hard drives, are recognized as sda, sdg, sdh, instead of sda, sdb, sdc as all the time before, and what i expect as the right sequence.
The DVD device is for both variants sr0, which is also correct.
If i boot the genkernel-2.6.33-gentoo-r2 on the same system, everything is fine. What could be the root cause, what kind of kernel config (i don't know) could be the reason for that?
As i mentioned, its the same system, so its the same udev rules, udev is on both runlevels present, nothing different except using the initrd for the hardware recognition.
Ok, not good for comparison that i'm using differnt kernels, so there are more possibilities as root cause, than using the same kernels for both. But hopefully you can help me anyway, cause you know thes kind of trouble - right?
Some info:

Ok guys, no ideas after such a long time, astonishing.
When i checked my devices via ls -lsa /dev/disk/by-id i found out that my Card Reader has been recognized before my other hard drives:

So i checked my kernel.config, and found out that the option USB_STORAGE was built into the kernel, so I tried to select it as module and compiled it again.
Here's the result as it should be.

So the case ist solved for me.

I have had the same problem and I reverted to 2.6.33 for now.

This is not a solution. It is a workaround... In my case, my 3 AHCI hard disks are all on the same controller, and still, with gentoo-sources-2.6.34-r1 I get the following:
/dev/sda: SATA disk 1
/dev/sdb: SATA disk 2
/dev/sdc: Card reader 1
/dev/sdd: Card reader 2
/dev/sde: Card reader 3
/dev/sdf: Card reader 4
/dev/sdg: SATA disk 3
The first two SATA drives are recognised, then the card reader devices, then the third SATA drive.
Is this a known bug?
