Yes, I know - SMP kernels are unsupported :) I was just wondering if these problems are known and/or fixed in the development kernels that were talked about on this list recently. Any time I try to run a heavy compilation job, I get: # cd /usr/src/sys/ia64/compile/xxx # make -j4 kernel [...] ../../../cam/cam_queue.c:82: Internal compiler error in rtx_needs_barrier, at config/ia64/ia64.c:4685 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://www.gnu.org/software/gcc/bugs.html>; for instructions. *** Error code 1 1 error Single threaded compilation (without -j4) is mostly fine, but occassionally results in the above error message (Especially compiling large C files that make up gcc itself). This one is a 2 cpu Itanium box. Interestingly, the box never panics outright. -Arun To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ia64" in the body of the message
