Dave, here is the original message where my reply was bounced by vger as taboo. as the dmidecode was not in-line, I selected it in the attachments pane of kmail and highlighted the lines I wanted to reply to, clicked reply, and they were put in a window for me where i added some text and hit send. unclear at this point how to convince kmail how to not send in a format that offends vger. -Len ---------- Forwarded Message ---------- Subject: dmidecode acpi_osi=!Linux Date: Saturday 14 July 2007 08:16 From: "Gerard de Vos" To: linux-acpi@vger.kernel.org Hi, I got this in my dmesg: ACPI: System BIOS is requesting _OSI(Linux) ACPI: Please test with "acpi_osi=!Linux" Please send dmidecode to linux-acpi@vger.kernel.org acpi_osi="!Linux" makes a big difference on this laptop. If I boot without it the system hangs on boot unless I specify "noapic". noapic in turn generates a lot more interrupts that have to be handled by irqfixup or irqpoll.
