Hello Nikolay, First thanks for helping! I tried to recompile the kernel (2.6.31 of the ubuntu sources), i disabled the SMP support, CONFIG_SND_HDA_POWER_SAVE was already unset so i tried to set it as 0, using the new kernel i brought done all interfaces, unloaded many modules, connected successfully, i could ping and send 10 icmp packets but then the network stopped again and pppd crashed (just like before), when reconnecting it gave me a segfault (so again, just like before), the dmesg output is a bit different: [ 539.463626] ------------[ cut here ]------------ [ 539.463629] kernel BUG at kernel/timer.c:762!
