process hanging on 7.2-PRERELEASE

[Ronald Klop]

Hi,

My brand new amd64 has a hanging process.
# uname -a
FreeBSD sjakie.klop.ws 7.2-PRERELEASE FreeBSD 7.2-PRERELEASE #0: Wed Mar  
25 00:07:31 UTC 2009     root at dhcppc0:/usr/obj/usr/src/sys/GENERIC  amd64

I'm compiling a port of kde4.
top says this since a while:
43404 root          1 116   20 21304K  4148K umtxn  1   0:00  0.00%  
automoc4

# procstat -kk 43404
   PID    TID COMM             TDNAME           KSTACK
43404 100279 automoc4         -                tdq_cpu+0x1218

Dmesg in the attachment.

Can I provide more information to debug this?

Ronald.
