Only with "acpi=off" the system started completely, and I was able to log in into gdm, and later switch it off in normal way (crash8.txt). With other parameters kernel panicked during the boot. I attach the crashes.tar.z2 file containing logs (crash?.txt) and configuration of my kernel (config). Hardware details of my machine were already provided in previous messages in this thread. -- Regards, Wojtek -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
