I'm using the the 2.2.16-35 smp kernel and a 3c905 netcard.The network hangs after a varying time without error messages (very similar to
22717and bug 22583). The way to get it back working is to stop the network unload the netcard module, load it again and restart the network.
The time until the network hangs seems to depend on how much you use the network. Usage seems to prolong the time and vice versa. I
think it has to do with auto-cleaned modules though, but rather a kernel/driver problem. I get the same problem when I load the modules by
hand without the "auto clean" flag set. Removing the kmod script does not change the situation either. Also, when the network is hanging,
lsmod still reports the netcard module as loaded and used. The problems still needs a solution though, since the networks always hangs after
1-3 days (depending on usage) of uptime on all my RedHat 7.0 machines. I would be greatful for hints on solution. The ping trick (every 5
minutes) doesn't work for me. The same hw-components and configuration worked well before upgrading to the current kernel.
Steps to Reproduce:
1. boot the machine
2. wait 1-3 days
3. it seems to happen faster with less network usage
Actual Results: The machine is unreachable from the network (even with ping) the network is also unreachable from the machine. Also the
netstat -r shows no route via eth0. Just restarting or reloading the network doesn't help.
Expected Results: as above
I also upgraded glibc to version 2.2-12 and xinetd to version 188.8.131.52pre11-1 when I upgraded the kernel. The change of xinetd seems unlikely
have anything to do with the problem, but upgrading glibc might well have some implication
This should be long fixed. If not then feel free to reopen it against the
current errata kernel
