Hello! I would like to report a kernel bug. All kernels after version 2.6.17-1.2187_FC5 get my computer crashing sooner or later, after reboot with a later kernel version. With 2.6.17-1.2187_FC5, all works fine. The kernels I've tried after this one, is: kernel-2.6.18-1.2239.fc5, kernel-2.6.18-1.2200.fc5 and kernel-2.6.18-1.2257.fc5, and all of them crashes after some minutes or hours or after a few days, at least. What I've noticed, is that it may have something to do with the network. I've three network cards on the system, and I think the crash problem can has to do with eth2. There are two modules related to the network cards that are loaded, e100 and 3c59x. I'm not 100% sure which of them are serving two cards, but I think it is the last one, 3c59x. The crash problem behaves as follows, I'm blind, so I cannot see what's comming on the screen. I'm only using the text console (no GUI): - The braille display stop responding (I'm using the screen reader 'BRLTTY'.) - I hear several beeps with about 1 sec. pause between, which I suppose comes from the 10 'screen' sessions in the current console. - Sometimes I'm able to press Ctrl-Alt-Del to reboot, and after that, all hangs. Sometimes I'm not able to do so. - I allways need to do a hard reboot.
