These are the only changes that I'm missing - Edit src/share/man/man9/Makefile,v Add delta 1.6 2004.05.05.16.57.11 hmp Edit src/share/man/man9/bus_alloc_resource.9,v Add delta 1.3 2004.05.05.16.57.11 hmp Edit src/sys/kern/kern_lockf.c,v Add delta 1.9 2004.05.05.09.17.04 joerg Edit src/sys/kern/tty.c,v Add delta 1.9 2004.05.04.23.22.43 dillon Edit src/sys/libkern/strcat.c,v Add delta 1.5 2004.05.05.00.17.44 hsu Edit src/sys/libkern/strcpy.c,v Add delta 1.6 2004.05.05.00.17.44 hsu Edit src/sys/libkern/strncpy.c,v Add delta 1.5 2004.05.05.00.17.44 hsu Edit src/sys/netinet6/ip6_input.c,v Add delta 1.15 2004.05.04.23.08.43 dillon Edit src/sys/sys/bus.h,v Add delta 1.12 2004.05.05.16.57.11 hmp Edit src/sys/sys/libkern.h,v Add delta 1.7 2004.05.05.00.17.45 hsu > Even so, the are likely still issues with the FP code in the current > up-to-date source tree, which I've been tracking down with the help > of David Rhodus.

Since I can so readily reproduce this feel free to throw some patches my way :) :) ... > -Matt -------------------------------------------------------
