Due to many interrupt-level buffer overflows I can not use this card to establish TCP-connections via modem (initial telnet handshake did work whilst the card shared its irq with the adaptec- controller - the card should have its own irq now after I put it in a different PCI- slot).. This looks like PR 51982 Feb 27 21:03:17 dialout kernel: sio12: 24 more interrupt-level buffer overflows (total 433) Feb 27 21:03:56 dialout kernel: sio12: 178 more interrupt-level buffer overflows (total 611) Feb 27 21:04:13 dialout kernel: sio12: 71 more interrupt-level buffer overflows (total 682) Feb 27 21:05:56 dialout kernel: sio12: 172 more interrupt-level buffer overflows (total 854) Feb 27 21:06:06 dialout kernel: sio12: 79 more interrupt-level buffer overflows (total 933) Feb 27 21:06:07 dialout kernel: sio12: 4 more interrupt-level buffer overflows (total 937) Feb 27 21:07:56 dialout kernel: sio12: 23 more interrupt-level buffer overflows (total 960) Feb 27 21:08:06 dialout kernel: sio12: 26 more interrupt-level buffer overflows (total 986) Interestingly, this only happens with the PCI-800H, but the system also has an older 8-port ISA-Card that works without any problems. And yes, the system is an old and slow PIII with 500 MHz only, but I have this problem even if only one modem is in use (sio12). I also don't know why the card can't use fast mode, unless this is because it looks like 2 cards with 4 ports that share an irq. All help/ideas really appreciated!
