A brief description of system is (dmesg attached): Tyan S2510 dual 1Ghz RELENG_6 From Aug 14 GENERIC Reboot hangs after displaying "cpu_reset: Stopping other CPUs". This appears to be a hard lockup, as I cannot break to the debugger. In an effort to see where the problem was, I amended src/sys/i386/i386/vm_machdep.c src/sys/kern/subr_smp.c Adding some printf statements and removing the #ifdef DIAGNOSTIC in subr_smp.c, so that it printed always (diffs attached). To my surprise, after a kernel rebuild + shutdown and restart, I find that 'shutdown -r now' and 'reboot' *now work*! Hmmm, nice but weird. This sort of voodoo suggests something like memory being clobbered somewhere... Hopefully this will help shed some light on this issue - and I am happy to try out any suggestions to diagnose. As an aside, this same thing happens with 5.4-RELEASE - but *only* after an SMP kernel has been built, so this appears to be similar to prs i386/36943, i386/34092.
