Here is wha vmstat -i says ...

feuer# vmstat -i
interrupt                          total       rate

Hmm, there is nothing on irq7 ...

I'll take a look in FreeBSD PR Database later, but at the moment i'm not
sure, that raid5 already is implemented in gvinum. I've read only about
raid 0, 1 & 3. But i found some files in 

usr/src/sys/contrib/dev/hptmv/raid5n.h
usr/src/sys/dev/vinum/vinumraid5.c
usr/src/sys/geom/vinum/geom_vinum_raid5.c
usr/src/sys/geom/vinum/geom_vinum_raid5.h
usr/obj/usr/src/sys/SERVER/modules/usr/src/sys/modules/geom/geom_vinum/
geom_vinu m_raid5.o
usr/obj/usr/src/sys/SERVER/modules/usr/src/sys/modules/vinum/vinumraid5
.o

which looks like the required files (???). Does someone know something
about gvinum raid5 support or has a working system?

Interesting is too, that it works fine with 5.2.1 and vinum on the same
machine.

And keep in mind, that i'm a newbie and still learning, so it's
possible, that the "problem" is sitting in front of the monitor ... but,
i think, in this case i made nothing wrong (See attached files from the
original post), but, who knows ... ;-)

Cheers

Steffen
