Hi!
I've got a problem when accepting calls in asterisk from a HFC-PCI card.
Asterisk dumps core with the following
backtrace. Any ideas what would this be?
Thanks for the backtrace, unfortunately I also need the "debug visdn *" trace
for the whole call in order to understand where the reference got lost,
please try to reproduce the bug with debugging enabled.
Bye,
Hi!
The debugging trace is included at the bottom. I should mention the
machine has a Via C3 CPU, but everything is compiled
for the i586 arch so that should not cause any problems. The kernel is
2.6.16.8 on Suse 10.1 beta 9.
The weird thing is, that I've tried a never version of the kernel
package, tried installing Fedora Core 5 or compiling the "vanilla"
kernel, yet all of them lack a symbol export for "dev_ioctl". To get
lapd.ko properly loaded, I added an EXPORT_SYMBOL(dev_ioctl);
to /net/core/dev.c and recompiled the kernel but I guess that is not the
correct solution? I'm not really a familiar with kernel programing
but is that an error in the kernel sources?
