Hi, I am really stucked here. Recently I bought one of those Sony Ericsson GC85 cards hoping it could replace the serial cable and my cell phone connected to my laptop. Unfortunatly it does not seem to work very well. The card is recognized as a generic modem on the pcmcia bus, and shows up as a cuaa (sio) device. I can talk to it without problems with cu and minicom. I've configured ppp to call my local ISP (Telenor) with GPRS. That works in some way. My modem gets connected and I can ping other hosts and do simple telnet commands to get data from webservers and other services. But, when connecting with ssh it just hangs. That happens when I try to get compressed data from the network as well. Some data: I'm running 4.11-STABLE on a Acer Travelmate 630 series laptop. The output from pccardd from startup shows this line after adding the sio-device as a generic modem: sio2: unable to activate interrupt in fast mode - using normal mode When trying to do some activity on the network after connecting this messages shows up in my log: sio2: xxx more interrupt-level buffer overflows (total xxx) (xxx is a number) I've read a lot of documentation on the net about this issue, and I think I've tried most of the tips and tricks suggested. I tried to change the irq assigned for the card without luck, I have set the cp4ticks to 4096 in sio.c (that removed the interrupt-level buffer overflows in the log, but then network still don't work as it should), I changed the list of available irqs in pccard.conf, and I really don't know what to do next. The irq seems to be hardcoded to 3, but in Windows it shows up with irq 7, which in the FreeBSD log I get a message like this: stray irq 7. The card works well in Windows, so I don't think is a hardware problem. Does anyone have any tips or suggestions on how to get this card to work properly with FreeBSD? Has anyone managed to get this card, or some of the other Sony-Ericsson GC-cards, to work at all with FreeBSD? Another one with the same problem as I (I guess) can be found here: http://lists.freebsd.org/mailman/htdig/freebsd-mobile/2004-May/003813.html PS. The reason why I don't run FreeBSD 5 is that it just don't work on thia laptop at all. regards, Espen Tagestad
