Hang while PXE booting todays -current

Is anybody else having trouble PXE booting -current as of today? I had a
working test setup where my laptop was PXE booted off of my -current desktop
box. The test setup was running yesterdays -current. Then I made world today
and now it hangs at the point it should start executing /sbin/init.

The last few lines displayed are as follows, transcribed from the laptop
screen as it does not have a serial port, so not serial console:

...
fxp0 at 192.168.176.10 server 192.168.176.1 server name DHCPserver boot file
pxeboot
subnet mask 255.255.255.0 router 192.168.176.1 rootfs 192.168.176.1:/ hostname
test.home.inlimbo.org
Shutdown interface fwe0
Adjusted interface fxp0
Mounting root from nfs:
NFS ROOT: 192.168.176.1:/

And here it hangs forever. I tried breaking into DDB. Doing a "trace" shows
this:

Also, earlier in the boot, I see this:

malloc() of "4096" with following non-sleepablelock held:
exclusive sleep mutex ifnet r = 0 (0xc05c79c0) locked _at_ nfsclient/bootp_subr.c:1696

The kernel is GENERIC with options BOOTP, BOOTP_NFSROOT and BOOTP_COMPAT
added.
