 Interesting - for me this has never happend before the following changes:
 
 cvs rdiff -u -r1.325 -r1.326 src/sys/dev/usb/ehci.c
 cvs rdiff -u -r1.40 -r1.41 src/sys/dev/usb/ehcireg.h
 cvs rdiff -u -r1.52 -r1.53 src/sys/dev/usb/ehcivar.h
 
 and downgrading those files to the 1.325/1.40/1.52 resp. makes my current
 kernel work again (note that I only did test very few sample runs of
 the full /usr/tests).
 
 Since this is touching cache alignment - could it be that we get the cache
 line size wrong on this machines?
