The kernel doesn't crash since Helge's stack backtrace fix. We are just getting a lot of segfaults in application code. I'm fairly certain libc6 in debian testing is still built with linuxthreads. I'm not sure libc is actually making futex calls, but one is compiled into _dl_fixup. I suppose I could add a printk in the kernel to see if futex's are being used. I'm currently building debian libc6. In a quick attempt, I wasn't successful in building the glibc cvs source. It pushes hard to get you to configure with nptl. My build with linuxthreads failed with a type size problem. I'll try the testsuite with this build on my current kernel. If that works, I'll flip to 2.6.28. Dave -- J.
