Dear list members, I'm trying to get a 3g / UMTS connection to work on my RELENG_6 (i386, AMD Sempron) machine. I've installed a Novatel Merlin U630 card (pcmcia) which is providing a hayes serial modem to the system (on sio4 in my case). Dialing works fine but most DNS queries are timing out, but also most tcp sessions won't work. While in ppp (userland) I'm seeing messages like: Phase: deflink: HDLC errors -> FCS: 28, ADDR: 0, COMD: 0, PROTO: 0 Phase: deflink: HDLC errors -> FCS: 27, ADDR: 0, COMD: 0, PROTO: 0 Phase: deflink: HDLC errors -> FCS: 102, ADDR: 0, COMD: 0, PROTO: 0 Phase: deflink: HDLC errors -> FCS: 25, ADDR: 0, COMD: 0, PROTO: 0 Phase: deflink: HDLC errors -> FCS: 9, ADDR: 0, COMD: 0, PROTO: 0 Phase: deflink: HDLC errors -> FCS: 10, ADDR: 0, COMD: 0, PROTO: 0 Later I'm seeing message like that on the console screen: sio4: 152599 more interrupt-level buffer overflows (total 152599) I've tried increased and decreased the baud rate in ppp but the same appears. dmesg for the devices involved: cbb0: <RF5C475 PCI-CardBus Bridge> at device 13.0 on pci0 cardbus0: <CardBus bus> on cbb0 pccard0: <16-bit PCCard bus> on cbb0 pccard0: Allocation failed for cfe 7 sio4: <Novatel Wireless Merlin UMTS Modem> at port 0x2f8-0x2ff irq 17 function 0 config 15 on pccard0 sio4: type 16550A sio4: unable to activate interrupt in fast mode - using normal mode pccard0: Allocation failed for cfe 7 pccard0: Allocation failed for cfe 15 sio5: <Novatel Wireless Merlin UMTS Modem> at port 0x2e8-0x2ef irq 17 function 1 config 23 on pccard0 sio5: type 16550A sio5: unable to activate interrupt in fast mode - using normal mode It's a RELENG_6 machine with a recent kernel (compiled yesterday with kernel sources from Feb-26). The same appears whether or not SMP kernel is being used. I've been unable to find anything in the archives closely related. The card works fine under Win2k (on a different machine). The RELENG_6 machine is using a PCI-PCMCIA adapter. Any hint is welcome! :) Is there a workaround? Should I go with pppd or mpd? Do you need any more info on that? Is there something more I might check out? What about the dmesg messages: pccard0: Allocation failed for cfe 7 sio4: unable to activate interrupt in fast mode - using normal mode As always, thanks a lot for your help! Volker
