I'm running latest RELENG_5 (already with acpi_pci_link.c and get:

'Interrupt storm detected on "irq5: uhci0 uhci1"; throttling interrupt source'

stortly after the login prompt appears. Without acpi everything seems to work 

Mainboard is an ASUS CUV4X-D with latest BIOS (1016) and 2 PIII 1GHz.

dmesgs of verbose boots are here:
