Hi, I tried all the permutations of the above with the same result: the kernel hangs at NET: Registering protocol family 2. With nolapic it hangs at APIC: Using PIC for interrupt routing With acpi=off it boots but, obviously, everything acpi related does not work. anything else I can try? The laptop does not have a serial port, so I can't capture the dmesg output. -- Best regards, Alessandro Zummo, Tower Technologies - Torino, Italy http://www.towertech.it
