Hi,
I've got a SonyEricsson GC89 GPRS/EDGE pcmcia card (serial), but I
can't get to work it (on my laptop Acer TravelMate 4152LMi).
The problem is that the connection is very, very slow (download rate
about 0,5KB/s) and I've got more then 20% rx errors on ppp0 interface.
The system (I tried FC5, FC7, Ubuntu 6.04, Ubuntu 7.04 and Ubuntu
7.10) can recognize this card, I can make ppp connection to GPRS/EDGE
network. But this connection is really very slow, and I think.
What I found is when I boot system with acpi=off parameter everything
works great, I' ve got transfers about 20-25KB/s with no rx errors on
ppp0 interface.
I'm really not sure if this problem is related to acpi subsystem
(maybe this is pcmcia or pppd problem), but I have to try.

I really don't know how to make this card working properly, and I need
your help.
If you need more specific info just tell me what do you want.
