    Hi,

    Just got a D-Link USB radio (R100) and I'm seeing lots of timeouts with
    it. I've seen this through the last few 2.4.1+ and -ac+ kernels.

    Current config:

    Dual P3-500 w/ 512mb of RAM
    Tyan Tiger 133 mobo with VIA chipset, onboard USB
    Kernel 2.4.1-ac9 compiled with egcs-1.1.2

    The only thing funky is that three devices are sharing an interrupt:

               CPU0 CPU1
      0: 216690 219652 IO-APIC-edge timer
      1: 3564 3816 IO-APIC-edge keyboard
      2: 0 0 XT-PIC cascade
      3: 7 20 IO-APIC-edge serial
      5: 1017 1135 IO-APIC-level EMU10K1
      8: 0 1 IO-APIC-edge rtc
     11: 22978 22756 IO-APIC-level aic7xxx, eth0, usb-uhci
     12: 64220 63272 IO-APIC-edge PS/2 Mouse
     14: 12132 12810 IO-APIC-edge ide0
     15: 3 10 IO-APIC-edge ide1
    NMI: 436327 436327
    LOC: 436151 436128
    ERR: 0

    The ethernet card is a 3Com 3c905, the SCSI card is Adaptec 7892B (19160
    card). No problems with either as far as I can tell, but one of these
    modules may not be playing nice with interrupt sharing.

    The messages:
