asterisk users - Oct 2005 - unloading TE110P bristuffed module cause kernel panic

Hi folks,

I've already searched the mailing list but no one else seems to have my
same problem.

I'm using Asterisk with the following configuration:

 

Fedora Core 4 (but I also tried Fedora 3)

 

1 Digium TE110P

1 TDM40B

1 HFC-S 'Cologne'

 

bristuff 0.2.0-RC8o (zaptel 1.0.9.2)

 

I compiled right, I can load kernel modules but when I try to unload
wcte11xp module (the one for TE110P card) I get a kernel panic: 

Kernel panic - not syncing:
/usr/src/bristuff-0.2.0-RC8o/zaptel-1.0.9.2/wcte11xp.c:333:
spin_lock(usr/src/zbristuff-0.2.0-RC8o/zaptel-1.0.9.2/wcte11xp.c:d964000
4) already locked by
/usr/src/bristuff-0.2.0-RC8o/zaptel-1.0.9.2/wcte11xp.c/887. (Not
tainted)

 

This happens if I load and unload by zaptel script or if modprobe or
insmod 'by hand', then run ztcfg and the unload the module.

No bristuffed zaptel works right and bristuffed zaptel module for TDM40B
works right.

 

The card does not share IRQ with other devices, anyway  I tried to have
only TE110P mounted on PCI slot and to change PCI slot where card is
mounted. Nothing to do.

 

I really don't know what else I can try.

 

Thanks for help,

_fangi_

Same problem with debian sarge on a dell and asterisk 1.0.7 from 
packages, unloading the module freezes the system, (rebooting the 
machine worked right), I installed zaptel 1.2beta and it seems to work, 
but I haven't really tested it, only loaded/unloaded/loaded and placed a 
couple of calls.
