Yes, I have, using Azureus under Sun 1.5.0 (and now _01). Lockups (usually so hard I can't alt-sysrq-b), and sometimes spontaneous reboots. I also can't get through more than a couple eps of Buffy in mplayer without lockage, and running folding@home overnight seems to do the trick too. I've tried backing off to the 741 kernel (FC3), and while that's better, it's still not crash-free. Unfortunately, my hardware has a bad history, and I'm still in the process of making sure it's not at fault before I bugzilla anything. I had a power supply die last year, which may have been the reason my GeForce 256 died somewhat later... I'm now running on a borrowed Permedia 2V card, the health of which the lender wasn't entirely sure of either. I'm planning on picking up a cheapie GF4MX card today to see if that helps things. If you haven't already, definitely give your hardware at least an overnight run of memtest86+. I found that with my bios set to 'turbo', the memory timings were just a little too aggressive such that I was getting a few sporadic errors on test 6 in high memory. An initial 1-pass run I had done when I first enabled the setting hadn't exposed that problem. Setting it back to 'normal' fixed the memory errors, but unfortunately hasn't ended the crashes. Of course, it's all moot right now because I have yet to get a single oops or panic message to report... Other than the video cards, my hardware is an Athlon 1700+ (1466 MHz) on a Soyo SY-K7V Dragon Plus mobo (VIA KT266A), plus an extra ethernet card (tulip), SCSI (2940UW), and an extra Promise 100TX controller. Lots of drives. Any similarities to your hardware? I run with vm.swappiness set to 0, but I'm not sure if that has any bearing on the problem. --wes
