Network fails with USB install

  • Please and thank you for some hints, where to do the work.

    Slack 9.1 as Linux version 2.4.22 (root@midas) (gcc version 3.2.3) #6
    as Intel Pentium MMX 200 MHz.

    Install has run with Intel 82557-based Ethernet LAN Adapter v3.00 (970625), since new, some weeks back. Card was reconfigured for NO PNP, per numerous posts regarding this card balking Linux in older modles pnp enabled and where Linux originally did not configure the card. Network has worked fine, since.

    Linux finds and enables Eth0, fine in static or dynamic allocation and has worked fine until USB installation yesterday.

    USB card is... w670 USB universal v2.0 CMD 0670B-400

    Following installation, access to eth0 returns "network unreachable" in either static or dynamic, yet configuration finds and establishes eth and seems none the wiser.

    I can ping the card itself internally. I cannot ping to any other address, LAN or outside and cannot ping the router, and no other machine on the network can ping this machine's node.

    Syslog shows the Ethernet card established at INT10, mac address is established, but then USB seeks INT 10 and fails.

    I'm new enough to Linux that I don't know how interrupts get handled and am wondering if this is an interrupt conflict, interfering with the LAN card and USB both.

    Pertinent Sylog clip:

    Apr 16 00:05:59 Linux1 kernel: 8regs : 218.400 MB/sec
    Apr 16 00:05:59 Linux1 kernel: 32regs : 174.400 MB/sec
    Apr 16 00:05:59 Linux1 kernel: pII_mmx : 300.400 MB/sec
    Apr 16 00:05:59 Linux1 kernel: p5_mmx : 364.800 MB/sec
    Apr 16 00:05:59 Linux1 kernel: raid5: using function: p5_mmx (364.800 MB/sec)
    Apr 16 00:05:59 Linux1 kernel: VFS: Mounted root (ext3 filesystem) readonly.
    Apr 16 00:05:59 Linux1 kernel: eth0: 3c5x9 at 0x300, 10baseT port, address 00 a0 24 0a 94 12, IRQ 10.
    Apr 16 00:05:59 Linux1 kernel: eth0: Setting 3c5x9/3c5x9B half-duplex mode if_port: 0, sw_info: 0921
    Apr 16 00:05:59 Linux1 kernel: eth0: Setting Rx mode to 1 addresses.
    Apr 16 00:05:59 Linux1 kernel: usb-ohci.c: request interrupt 10 failed
    Apr 16 00:05:59 Linux1 kernel: Trying to vfree() nonexistent vm area (c6850000)

    Do I need to reorder the Interrupt assignment? I have not seen how Linux maps Irq's or if dynamically, so I'm a little unsure where to start, to make these determinations.

    Thanks again. All help is truly appreciated
