Ok, I found why this bug triggered. I had newer glibc (2.7) than in etch, probably from testing, but old initramfs-tools. (probably i was testing newer kernel (2.6.24) with my second gigabit network card, but now i don't use it) Downgraded to etch and 2.6.18-6-xen-686 with unpatched initramfs-tools helped, and now everything works. Sorry for wasting your time. Bug can be closed. Thanks again. -- Witold Baryluk
