Maybe the is to wait for stable 2.6.13 before doing tests with realtime-preempt as it gets updated twice a day.

That compiled fine with 2.6.12-RT-xx, but 2.6.12-RT didn't work very well here. it hardlocked and performance whise there was not much difference to vanilla. 2.6.11-RT + reiser4 works fine, but to be able to get some sound out of my second soundcard i need a recent alsa-cvs, which doesn't compile with kernel < 2.6.13-rcX. The above reiser4 patch is broken with 2.6.13-rc4-RT again. > > > fs/built-in.o(.text+0x929a9): In function `reiser4_put_super': > > : undefined reference to `rcu_barrier' > > fs/built-in.o(.text+0x97989): In function `_done_sinfo': > > : undefined reference to `rcu_barrier' > > fs/built-in.o(.text+0x97d76): In function `_done_formatted_fake': > > : undefined reference to `rcu_barrier' > > fs/built-in.o(.text+0x97d86): In function `_done_formatted_fake': > > : undefined reference to `rcu_barrier' > > make: *** [.tmp_vmlinux1] Fehler 1 > > > > ----->8----- > > > > Maybe some has managed to fix that or knows how to do so and is > > willing to help me.
