Are there really any substantial changes in kern_sig.c and kern_switch.c that would affect the stability of 5_STABLE (and does UMA in 5_STABLE ensure thati proc_fini() won't be called?) I'd just contend that in the case of my system, 5_STABLE with the 4BSD scheduler is not stable, or at least the script I'm running is somehow exhausting system resources to the point that the system becomes unusable, and this problem isn't exhibited with the ULE scheduler. Regardless, the script was causing the 5.3-RELEASE GENERIC kernel to panic, and rendered the system completely inaccessible with a kernel built from the latest (as of about 5 days ago) RELENG_5 kernel with the 4BSD scheduler. So, I'd be very grateful if ULE could be merged into RELENG_5 as it would dramatically improve the stability of at least my server. Has anyone else with a dual amd64 system had problems like this post 5.3-RELEASE? I know crashes under heavy MySQL load on dual amd64 systems were a problem before, but I thought that had been resolved. Tony Arcieri
