DMAR error message and stack trace Both the working and desktop kernel configs include CONFIG_DMAR This appears to be a BIOS bug, but should probably be filed as a separate bug against PCI -- it is possible that the stack trace is not useful here and perhaps should be removed from the kernel. 2. [Firmware Bug]: Invalid critical threshold (_CRT:%) This one is a BIOS bug. It is due to Linux claiming suport for "Windows 2006". The BIOS has invalid code for vista, and you can get rid of this message by booting with acpi_osi="!Windows 2006" acpi_osi="!Windows 2009" though living with the message is also fine. 3. ACPI warnings related to \_SB_.PCI0.PEGP.VGA_ (LCD and VGA) This is a third BIOS bug, as explained by Bob in comment #12. If the LCD brightness controls work on this box, then just ignore these warnings. 4. ssb b43 driver issues -- apparently causing a hang. this, the most serious issue, is likely the only regression, and is likely a duplicate of bug 14716 Finally, the difference between the install kernel and the desktop kernel is indeed a mystery. the configs are very similar, mostly changing suport between =y and =m. The ACPI support is identical, and both include ssb. In summary: 1. file a PCI bug 2. documented BIOS bug 3. documented BIOS bug 4. duplicate this sighting is closed. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
