Ingo http://bugzilla.kernel.org/show_bug.cgi?id=12940 Summary: CONFIG_DMAR/CONFIG_DMAR_DEFAULT_ON makes the kernel unbootable Product: Platform Specific/Hardware Version: 2.5 Kernel Version: 2.6.29 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: x86-64 AssignedTo: platform_x86_64@kernel-bugs.osdl.org ReportedBy: edman007x@mac.com Regression: No When i enable the options CONFIG_DMAR/CONFIG_DMAR_DEFAULT_ON my kernel fails to boot. It just hangs at: hpet0: at MMIO 0xfed00000, IRQs 2, 8, 0 hpet0: 3 comparators, 64-bit 14.318180 MHz counter right before that i see stuff saying that the IOMMU was remapping stuff. When i encountered this i recompiled the kernel, disabled only CONFIG_DMAR/CONFIG_DMAR_DEFAULT_ON and my kernel worked fine.
