/*
 * running the l2 cache as write-back and using cached memory for
 * usb data structures yields spurious errors such as
 *
 *      qhintr: td 0x60ee3d80 csw 0x8824a error 0x48 transaction error
 *
 * from usbehci.  so, at least for now, we will use uncached memory until
 * we sort out the write-back problems.
