Found one bug in that area: the assert (conditional on RT_DEADLOCK_DETECT) was done a bit too early, i have fixed this in my tree and have uploaded -51-02. > BTW, -50-44 through -50-51 wouldn't compile on the UP Athlon box. do the 51-02 (and later) kernels work on the UP Athlon box? > -50-43 appears to be rock-solid under the UP non-debug config.
