Summary: DMAR errors and driver instability
Product: Platform Specific/Hardware
Version: 2.5
KernelVersion: 2.6.29-rc3
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: x86-64
AssignedTo: platform_x86_64 at kernel-bugs.osdl.org
ReportedBy: adi at vmware.com
Latest working kernel version: unknown
Earliest failing kernel version: 2.6.28, earlier?
