The : laptop will not respond to CTRL C. I have to do a hard : reboot. I get the following messages just before the hang: : : sio4 <Intelligent PCMCIA FAX + MODEM> at port 0x2f8-0x2ff irq 11 : function 0 config 23 on pccard 0 : sio4: Type 8250 or not responding : sio4: Unable to activate interrupt in fast mode - using normal mode. : : After this last message the laptop hangs and I must press the power : off button. Any advice on what may be wrong would be : appreciated. The manufacturer claims that it uses a Hayes : AT compatible command set. Theis PCMCIA modem also works under Linux. sounds like a possible interrupt storm, or the modem isn't getting mapped to the address we think it is (see the 8250 message, there are no 8250 pcmcia modems), so the first interrupt we get, we spin forever in siointr. I think I'm going to put code into the pcmcia attachment that actively fails to attach to 8250's on pcmcia. Can I get a more complete dmesg? I assume that the sources are from June 1?
