 Posted: Wed Dec 07, 2005 2:29 am Post subject: modprobe snd-usb-audio fails using kernel modules [SOLVED] |
 |
|
I have a strange problem. I have been using ALSA modules from the kernel for some time without issue. I know they worked on gentoo sources 2.6.13.
They still sort of work now. Only with one problem, snd-usb-audio fails to load.
| Code: | # modprobe snd-usb-audio
WARNING: Error inserting snd_hwdep (/lib/modules/2.6.14-gentoo-r2/kernel/sound/core/snd-hwdep.ko): Unknown symbol in module, or unknown parameter (see dmesg)WARNING: Error inserting snd_rawmidi (/lib/modules/2.6.14-gentoo-r2/kernel/sound/core/snd-rawmidi.ko): Unknown symbol in module, or unknown parameter (see dmesg)

Assuming that it is a problem with versions of modules I have tried the following...
| Code: | # ls /usr/src/ -l
lrwxrwxrwx 1 root root 22 Dec 6 19:33 linux -> linux-2.6.14-gentoo-r2
drwxr-xr-x 19 root root 1304 Dec 6 21:45 linux-2.6.14-gentoo-r2
# uname -a
Linux max 2.6.14-gentoo-r2 #3 PREEMPT Tue Dec 6 21:14:27 GMT 2005 x86_64 AMD Athlon(tm) 64 Processor 3500+ AuthenticAMD GNU/Linux
# rm -rf /lib/modules/2.6.14-gentoo-r2
# cd /usr/src/linux
# make clean && make && make modules_install
# mount /boot
# cp arch/x86_64/boot/bzImage /boot/kernel-2.6.14-gentoo-r2-max1
# cp .config /boot/config-2.6.14-gentoo-r2-max1
# umount /boot
# reboot
# modprobe snd-usb-audio |
...same result as before. The rest of my ALSA setup works fine.
| Code: | # lsmod

I have searched the forums and found no mention of this problem. Any advice would be most welcome.
SOLVED
I have solved this problem. For some reason the following kernel options will cause this error...
| Code: | General setup --->
[*] Automatically append version information to the version string
Loadable module support --->
[*] Module versioning support (EXPERIMENTAL) |
Turn them off and all works fine. Looks to be a kernel bug. I shall see if it is already reported and if not post a report to the correct list.
On a side note I have checked and these get activated automatically by a make oldconfig without asking the user. I guess this is why we are warned not to use it when upgrading kernel versions for anything other than minor releases.  |

I have a similar problem as yours. I have in-kernel ALSA. snd modules fail to load at boot.
I have made exactly the same things as you have done in order to fix the problem, including disabling the two kernel options, as of above. But my problem persist:
| Code: |
# modprobe snd
FATAL: Error inserting snd (/lib/modules/2.6.14-gentoo-r2/kernel/sound/core/snd.ko): Unknown symbol in module, or unknown parameter (see dmesg)
#

If anyone has an idea, please help[/code]
