Yes, just try booting "-s" and go into single user mode to start with. Give a few commands, eg: 'sync; sync; sync', do a fsck if it's needed and then start multiuser.. If it then works as expected, then I suspect you are seeing a manifestation of a long running problem. I've found that SMP and/or ELF are unhappy at boot under SMP (and have been for 12 months). If I have /usr/libexec/getty dynamically linked and have more than a couple enabled in ttys, I get a lockup. The same happens if running rc5des/rc564 from the rc scripts if I don't go into single user and run a few commands first. At the time I hacked init(8) to do a couple of fork/exec's at startup and the problem went away. I don't understand what's going on and spent a fair while last year trying to figure it out. I'm pretty sure it's not ELF itself, it's just triggering something else. > John > -- > John Hay -- John.Hay@mikom.csir.co.za > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-smp" in the body of the message > Cheers, -Peter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
