So I've been having networking problems with the soekris. I tried changing to the -486 debian kernel, then I tried a 2.6.32 kernel that's linked to on the wiki and that seems to have solved the weird problems I was having including htop showing 100% cpu. -- Thomas Fjellstrom tho...@fjellstrom.ca _______________________________________________ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
