make buildkernel for GENERIC 9-STABLE just hangs, no error

[Olav Grønås Gjerde]

I have a weird problem while building the GENERIC 9-STABLE kernel. After
around 5 minutes of compile time, the process just hangs on same place. No
error. I've tried compiling different commits from this week with the same
result.

The part in the buildkernel process that hangs is this:
MAKE=make sh /usr/src/sys/conf/newvers.sh GENERIC
/usr/local/bin/svnversion
cc -c -O2 -frename-registers -pipe -fno-strict-aliasing  -std=c99 -g -Wall

vers.c
ctfconvert -L VERSION -g vers.o
linking kernel.debug
ctfmerge -L VERSION -g -o kernel.debug ............+ alot of *.o

Any suggestions?
