Subject: Oops in sound module when module unloaded...
Date: Sun, 16 May 1999 11:15:28 +0000 [thread overview]
Message-ID: <marc-linux-sound-92688304708240@msgid-missing> (raw)
Hi,
This happened just now under 2.2.9 but has happened before under 2.2.x
which I *think* was 0 or 1.
It seems to happen if I unload my sound module and then play something.
(I have a script run from cron that plays x sounds at x o'clock.)
Here's the oops:
---
Options used: -V (default)
-o /lib/modules/2.2.9/ (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-m /usr/src/linux/System.map (default)
-c 1 (default)
You did not tell me where to find symbol information. I will assume
that the log matches the kernel and modules that are running right now
and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
Warning in compare_ksyms_lsmod, module sscape is in lsmod but not in ksyms, probably no symbols exported

The module seems to get stuck after that meaning I can't rmmod or
modprobe -r it.

I don't really understand what all this means. If anyone wants to give
me a patch to try out though, I'm happy to try it.
My soundcard is an Ensoniq Soundscape PnP card which has been working
fine unless I remove the modules it seems.
/dev/sndstat looks like this:

Hope someone can at least tell me what all this means.
