asterisk users - Jun 2012 - Asterisk 10/1.6.1 and Dahdi/Libpri compatilities in BRI /PtmP

Hi,

After an upgrade, I discovered yesterday strange things I would like
to share here.

Basically, I'me comparing platforms:
The first one is a 2.6.26 (Debian Lenny) platform, with Asterisk
1.6.1.18, Libpri 1.4.10.2, Dahdi revision 8853 (must be between 2.3
and 2.5, I think).
The second one is a 2.6.32 (Debian Squeeze) platform, with Asterisk
10.5.1, Libpri 1.4.12, Dahdi 2.6.1.
Both are connected to telco BRI lines in TE/PtmP mode through a
Junghanns QuadBRI board (wcb4xxp driver).
Both handle incoming and outgoing calls correctly, as far as I can tell.

But on the second one, though working fine, Dahdi keeps showing alarm
messages such as:
[71765.784120] wcb4xxp 0000:01:0e.0: new card sync source: port 1
[71767.484151] wcb4xxp 0000:01:0e.0: new card sync source: port 1
[71771.184119] wcb4xxp 0000:01:0e.0: new card sync source: port 2
[71794.184164] wcb4xxp 0000:01:0e.0: new card sync source: port 1

and "pri show spans" mostly (but not always) report worrying status:
PRI span 1/0: Down, Active
PRI span 2/0: In Alarm, Down, Active

On the first box "pri show spans" constantly reports the line is up.

On thing to note is I had to forbid hfcmulti in modprobe.d in the
second box to comply with a warning from dahdi. Without that, I could
see this line in the output of lsmod:
mISDN-core

My previous message was incomplete.

mISDN-core  hfcmulti


1. What is the root cause that makes a board change its sync source ?
How can I check this ?
2.  How can I get rid of these alarms ?
3. Shall I report this ?
4. Waht would you suggest ?

Regards
