I hope some can help me as I am getting very frustrated. I have recently update my Fedora 6 to the latest kernel etc. and I am now experiencing some very strange, apparently random behaviour 1) All of a sudden the system starts going very very slow until it eventually hangs and has to be rebooted with the laptop power button
I've seen something similar. I have a box running mythtv which has 2 pvr500 tv cards in it. When all 4 tuners are recording, on a 2.6.19 kernel I'd see the load average get up to 5 or so, and the system would still be useable. With kernel-2.6.20-1.2933, the system would melt down - the load average would hit 20 or so and the only way to get sanity back would be to kill processes using a lot of memory (typically the X server). Rolling back to 2.6.19 made the problem go away. I haven't tried any newer kernel. I'm reluctant to blame the kernel specifcally (especially as I've not found anyone complaining about problems). I have a legacy nvidia graphics card, so I'm running nvidia-graphics9631-kmdl, plus ivtv-kmdl-2.6.19-1.2911 to drive the pvr500s. But as reverting the kernel (and thus the kmdls) fixed it, I concluded that there's something wrong with the kernel+kmdl combination. My system is quite old (athlon 2800+), but has 1.5Gb memory and the same amount of swap, and normally seems able to handle anything I throw at it. So in summary, try using a 2.6.19 kernel instead and see if it helps. Please report back here either way. Regards, Chris
