Hi again, I still have this problem with GPRS modem SonyEricsson GC89. What I found is if i boot system with kernel parameter acpi=off everything work great. I have got transfer about 20KB/s. When I boot with acpi enabled I have transfers about 900B/s and a lot of ppp0 rx errors (about 25%). I tried few Linux distributions (FC5, FC7, Ubuntu 6.04, Ubuntu 7,04, Ubuntu 7.10).
I still don't know if this problem is related to pcmcia (yenta_socket), but I have got no idea what and where should I look for. I really need to have this modem working, and I think I need Yours help. Grzegorz PS.
