I patched the kernel and rebuilt, then tested aviplay... success. Then I cvsup'ed, built/installed world and kernel, and started stress testing. I'm currently running two builds of X 4, one over NFS and one local, 'make cleandir' in /usr/src, AND avifile (ok, it's a little choppy, but still runs). I'd say it's probably safe to go back in the water again. Next stop, re-enabling softupdates. :) BTW, I'm probably wrong about this but looking at the patch it seems odd to me that one of these is ifndef and the other is ifdef: @@ -422,15 +433,21 @@ kmem_free(kernel_map, (vm_offset_t)old_ldt_base, old_ldt_len * sizeof(union descriptor)); FREE(new_ldt, M_SUBPROC); +#ifndef SMP + mtx_lock_spin(&sched_lock); +#endif } else { pcb->pcb_ldt = pcb_ldt = new_ldt; +#ifdef SMP mtx_unlock_spin(&sched_lock); +#endif } Just curious, Doug (Thanks BTW) -- I need someone really bad.
