Steps to reproduce: []# service iptables start
Also noticed same problem occurs with the ipv6 module. --------------------- ModProbe Begin ------------------------ Errors inserting modules: ipv6 (/lib/modules/2.6.15.4/kernel/net/ipv6/ipv6.ko) : Cannot allocate memory : 1 Time(s) ---------------------- ModProbe End -------------------------
Exact same problem (with iptables failing to load) on my system, kernel version 2.6.16.19
After some testing, it seems the problem goes away for me when I change CONFIG_ALPHA_GENERIC into CONFIG_ALPHA_MIATA (with additionally CONFIG_ALPHA_SRM). But CONFIG_ALPHA_GENERIC is supposed to work for miata as well, right? So this still remains a bug :( Hopefully this piece of information helps in tracking it down.
Was the problem resolved since, or still needs workaround in #3?
We sent our Alpha off to retirement some time ago so I can no longer test.
OK, please reopen if the problem confirmed with latest kernels.
