There is a single switch between them (tested with another one just to exclude a faulty switch). skge <--> Marvell 88E8001 chip 8139too <--> Realtek 8136B chip dmfe <--> Davicom DM9102 chip Symptoms are similar: tx timeouts and no more net activity. KDE desktop works, computational programs - work, the machine is usable, but cannot ping, nor can be ping-ed anymore. rmmod && modprobe the respective modules repairs the problem. Simple surfing/e-mailing from it do not trigger the problem. The machine is used as LTSP server for old PCs (as X terminals) (mostly outbound traffic) and is not usable as such due to this problem. The kernel is 2.6.24.2-SMP/x86_32 (PREEMPT or not - NO difference). As far as this happens with 3 different NICs/drivers could it be a problem in the (common for all of them) networking subsystem? As far as many persons are working on this machine only limited testing could be done. Thank you in advance for your suggestions, help (and patches). Regards.
