In kernel 2.4.0 in alloc_uhci when doing request_irq()

[Thunder from the hill]

Hi,

I am using an usual VIA MPV3 onboard USB device (on a AMD K6-II 400
machine), and it has ever worked fine on Linux (until including
2.4.0-test10). Now I wanted to use the "retail" 2.4.0-kernel, and USB
gets stuck while booting. Last messages are:
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
usb-uhci.c: $Revision: 1.251 $time 07:06:37 Jan 14 2001
usb-uhci.c: high bandwidth mode enabled
PCI: Assigned IRQ 10 for device 00:07.2
usb-uhci.c: USB UHCI at I/O 0xe400, IRQ 10
usb-uhci.c: Detected 2 ports
usb.c: new USB bus registered, assigned bus number 1

That's all.
I debugged a while and noticed that the error occurs beyond
drivers/usb/usb-uhci.c in the function alloc_uhci() after start_hc (s);
when calling request_irq(), the line reads:
	if (request_irq (irq, uhci_interrupt, SA_SHIRQ, MODNAME, s)) {
The called function crashes somewhere on top, as I noticed.
Is there a patch avariable, or should I do further investigation?
