Hartmann > > ohartman@klima.physik.uni-mainz.de I have a Tyan Tiger 133 dual P3 motherboard based on the via 694 chipset and I have not had any problems with it running in SMP mode except for one. If I run two instances of dnetc and then start up xmms the machine will eventually hang solid. Sometimes it takes a few minutes, other times a few hours, but once it hangs, nothing short of power cycling it will bring it back. I've been tracking -STABLE with this box for about 4 months, and have had the problem all along. I posted it to this list and it was described as a priority inversion problem causing deadlocks. Aside from this issue, the box is rock solid, it has been up for well over a month, often times with two copies of dnetc running the whole time. FWIW, I'm running two p3-600b/133 cpus, two 256 meg pc133 crucial SDRAMS, WD 30 gig ata/66 IDE disk, and a linksys LNE100TX nic. I can attach all sorts of stuff like a dmesg, or output from a verbose boot wor whatever if someone wants it.
