no, 

probably gcc-3.4 related. it builds fine on gcc-3.3 [debian unstable]

but S8 seems to have some other problems. I get xruns of more than 1 or
2ms [although the preempt timing reports normal max latencies around
200us] which i have only seen on S7 when the tmpdir wasn't mounted on a
tmpfs. SCHED_FIFO is ok, tmp dir is mounted on tmpfs. VP, KP, HIP, SIP,
BKLP are all enabled[see below]. Interesting enough i see the weird
jackstart pipe error when starting jackd with qjackctl, too[although
it's configured to use jackd directly]. What kernel was the other person
seeing this using?

from commandline looks all normal

basically i'd say: something's fishy about S8. I also wonder: the option
Preempt the big kernel lock shows up two times in menuconfig for me..
very weird.

I also got some dmesg stuff i've never seen before:

very weird [the ide probe stuff].. S7 was working very good..
