The machine works otherwise (with USB keyboard or over network). When rebooted in this state, the BIOS hangs with blank screen. I have the latest BIOS installed (P08). Old kernels worked. Bisection pointed to commit: b6dacf63e9fb2e7a1369843d6cef332f76fca6a3 (ACPI: Unconditionally set SCI_EN on resume) Commenting out this line in drivers/acpi/sleep.c: acpi_write_bit_register(ACPI_BITREG_SCI_ENABLE, 1); fixes the problem. Any ideas why this breaks on this system? -- Ondrej Zary -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
