Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-smp@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org I am currently experiencing problems with my FreeBSD system. I just recently go in my dual celeron/abit box in and have just started to use it. I am experiencing a strange problem I've never seen before. Whenever I do some intensive work, my computer will lock up. I still see my terminal screen, but it will accept no keyboard/mouse/network input. It won't even return attempted network connections, it just sits there dead for all intents and purposes and will stay like this for as long as I leave it(the longest being ~24H). I have to do a hard reset to reboot my machine, at which point it commes up fine (usually, although I have had to fsck the disk once when I did this). I do have an SMP system, however this problem occurs on either SMP or non-SMP kernel. This also occurs with and without runnning X. I am running 4.1-STABLE FreeBSD 4.1-STABLE with an SMP kernel. I have one IDE disk (DMA not used because of previous problems). I have a fairly vanilla kernel config. All SCSI entries have been removed, as have device entries for devices I do not have. It does not look like a hardware problem to me (no kernel panics, no reboots, etc). It does look like a deadlocking problem of some kind, but I havn't seen anything in the mail archive or the newsgroups recently about deadlocks (except for something unrelated I think). If you have any ideas please let me know. It's kind of annoying for my non-windows box to need a hard reset.
