    SubjectRe: ATI RS480-based motherboard: stuck while booting with kernel >= 2.6.15 rc1
    Time has passed without further mention of this problem. Today I took
    some time to discover exactly where the boot process was hanging. I
    found the place.

    In drivers/usb/host/pci-quirks.c, in function quirk_usb_disable_ehci
    (should start around line 211) there is a stanza that reads:

    /* always say Linux will own the hardware
    * by setting EHCI_USBLEGSUP_OS.

    pci_write_config_byte(pdev, offset + 3, 1);

    On my sapphire athlon64 motherboard (see the thread for more details),
    this call never returns (without generating any output). I commented
    it out, and now the EHCI subsystem works OK (currently running

    I do not know what the right patch should be.
