I am using an updated kernel, version: 2.6.12-1.1390_FC4 [This comment has been added as a mass update for all FC4 kernel bugs. If you have migrated this bug from an FC3 bug today, ignore this comment.] Please retest your problem with todays 2.6.12-1.1398_FC4 update. If your problem involved being unable to boot, or some hardware not being detected correctly, please make sure your /etc/modprobe.conf is correct *BEFORE* installing any kernel updates. If in doubt, you can recreate this file using.. mv /etc/sysconfig/hwconf /etc/sysconfig/hwconf.bak mv /etc/modprobe.conf /etc/modprobe.conf.bak kudzu Thank you. I upgraded to the new kernel: 2.6.12-1.1398_FC4 I still have the same problem, the speed I move my mouse somehow changes my transerfer rate. The faster I move my mouse, my transfer speed will increase. I'm compiling the 2.6.12.3 kernel from kernel.org and am tweaking out my laptop, I've noticed the Broadcom 4400 support is experimental for my Broadcom BCM4401 network card. Could this be a reason why I have the problem? I don't know what the Fedora Kernel 2.6.12-1.1398_FC4 support has for the network card, but if it also experimential I would think it may be the problem. FIX (sort of): I may have discovered that my network problem was tied to my partitioning setup. I've installed Fedora 4 many times all to this point without LVM. However, I cleanly installed Fedora 4 and have a 25MB boot, and 40GB LVM (39 GB root, 1GB swap). My page loads are fast and I get sustained downloads of 1MB/s - what I should get. So the mouse input/network speed is some weird anomoly that happens without LVM. I honestly can't think of any possible connection between the use of LVM and the behaviour you describe. That definitely is wierd. The earlier description sounded like a case of a mismatch between what hardware interrupt line is in use and what line the driver is monitoring. In a case like that, if the mouse was using the same interrupt line as the driver was monitoring, then moving the mouse might cause the driver to respond to incoming network traffic that it might otherwise not see. If you install FC4 (or later) again and see the network/mouse behaviour, I'd recommend that you try adding "acpi=noirq" or "acpi=off" to the kernel command line. Sometimes broken ACPI BIOSen can cause interrupt mapping failures like I described above. In the meantime, I'm not sure what to do with this entry. I think I will close it for the time being. Please reopen it if/when the problem comes back. Thanks! |
