Hi,

Could it be that your modem is a Mars chipset ?
see: =20
http://linmodems.technion.ac.il/packages/ltmodem/kernel-2.6/martian/MarsTes=
t.txt

Also I have seen comments about the module being not SMP compatible  unless=
=20
you boot up in UMP (uniprocessor mode).  It may be your case if you have a=
=20
dual core CPU.

Just my .02$,

        Regards,
