Please add “intel_iommu=on” for vmlinuz in your grub file to enable iommu which will disable the PMR DMA protection enabled by SINIT and use VTd DMA memory map to protect.

Thanks and best regards! Xinyue 在 2014-08-09, Sat, 21:23:58 ,Justin King-Lacroix 写到： OK, so Linux is starting. It could be a grub config issue. Stupid question, have you checked that your kernel is compiled with the TXT option enabled?

I think maybe it's a problem in grub. 在 2014-08-09, Sat, 20:24:37 ,Justin King-Lacroix 写到： How long are you leaving it before you assume it's failed? Reason is: the same thing happens to me, but it hasn't crashed, it's just kernel init taking a *very* long time (a good couple of minutes). Then my machine resumes booting and running correctly.
