i don`t know. it`s completely fresh compiled kernel, vanilla source. no binary modules .
can module-init tools be a reason? i upgraded that package because of depmod memory issue (https://bugzilla.novell.com/show_bug.cgi?id=371966 ). depmod was using >500mb on my system.

oh - and i didn`t tell that i`m in vmware, so this my trigger bugs which doesn`t easily happen on real hardware due to timing.
