Subject: DMI Info from Dell Latitude XT (and one weird ACPI issue)
Date: Sat, 18 Oct 2008 21:02:45 +0200 [thread overview]
Message-ID: <1224356565.5831.14.camel@localhost> (raw)
Hello,
linux kernel 2.6.27 dmesg output suggested to send following
information to this list:
[ 0.193980] ACPI: DMI System Vendor: Dell Inc.
[ 0.194138] ACPI: DMI Product Name: Latitude XT
[ 0.194298] ACPI: DMI Product Version:
[ 0.194456] ACPI: DMI Board Name: 0KT812
[ 0.194612] ACPI: DMI BIOS Vendor: Dell Inc.
[ 0.194770] ACPI: DMI BIOS Date: 08/28/2008
[ 0.194927] ACPI: Please send DMI info above to linux-acpi@vger.kernel.org
And to the second part of $subj -- after going to S3 state and then resuming, there is one strange ACPI error:

Oct 18 12:06:27 [kernel] [72428.864400] CPU1 is up
This error results in unability of the second core to change its
frequency -- whatever low or high the system load is, processes running
on CPU1 don't affect its frequency. If you have any idea what could be
wrong (or need any more data) please send me an e-mail.
Best regards,
