[Asterisk-bsd] FreeBSD-6/Zaptel-0.10 panic on startup

[Andrew Gordon]

Anyone else seeing this?

I have a system that was previously working OK with a TDM22B (= TDM400B +
2xFXO + 2xFXS) card under a fairly recent FreeBSD-5.x-stable and an older
version of the Zaptel driver (I think 0.9).

I decided to upgrade to RELENG_6 (sources from yesterday, approx
equivalent to FreeBSD-6.0-BETA1), and since I needed to rebuild the zaptel
modules to match the new kernel, I updated to the latest version from
ports, zaptel-0.10.

Now, the driver modules load and probe the card OK:

  Zapata Telephony Interface Registered on major 196
  FXS device: vendor=e159 device=1 subvendor=b100
  wcfxs0: <Wildcard TDM400P REV E/F> port 0xdc00-0xdcff mem
  0xdd004000-0xdd004fff irq 17 at device 10.0 on pci0
  FXS Attach for wcfxs0: deviceID : 0xe159
  wcfxs0: [GIANT-LOCKED]
  Freshmaker version: 71
  Freshmaker passed register test
  Module 0: Installed -- AUTO FXS
  Module 1: Installed -- AUTO FXS
  Module 2: Installed -- AUTO FXO
  Module 3: Installed -- AUTO FXO
  Found a Wildcard TDM: Wildcard TDM400P REV E/F (4 modules)

but any attempt to configure the card (either with ztcfg, or by starting
Asterisk) causes an immediate crash with what looks like an
indirection-through-null-pointer.

I haven't yet managed to get a meaningful backtrace from the resulting
core, but if this problem isn't known already I will try harder to get
one.

I have rebuilt both the kernel and the zaptel modules (via portupgrade -f)
to ensure modules and kernel are in sync.

Any suggestions greatly appreciated.
