#319 Interrupt problem



I have a severe problem with the interrupts of the pcmcia
port and a Cisco Aironet 340 card:

When there is high network traffic and I use the
keyboard, it often
occurs that both the keyboard and the network device
freeze. The
machine itself remains running (mouse is usable), but
needs to be
rebooted (which, btw, doesn't work completely because
under these
circumstances the machine fails to unload the usb
driver). I couldn't
figure out whether it is a problem of the pcmcia or the
driver. A minor problem is that the wavelan card often
hangs for a
few seconds or has very low throughput, which could be
caused by the
same problem.

I have a Dell Inspiron 3800, using 2.4.20 Linux,

    You could try bumping the wireless card onto a different
    interrupt and/or IO port range, by excluding the current ones
    in your /etc/pcmcia/config.opts file. It seems unlikely that
    this will help but I don't have any better ideas at the moment.

    Changing the interrupt did not help, but I managed to get
    a dmesg report from the crashed machine. It seems to be
    a problem of the aironet driver:

    Sounds like you should probably report this to the author of
    the airo driver, Ben Reed <breed@users.sourceforge.net>.
