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
2.6.16rc2).

I do not know what the right patch should be.
