dma_mapper_iommu loaded 卡住

网上说要拆显卡，但是是集显没办法弄，可以用其他linux启动

1. Boot with a debian or ubuntu live cd

List your drives / partitioned: Open a terminal window

2. type parted -l

Mine was sda5

3. mount /dev/sda5 /mnt

4. ls /mnt/

5. cp /mnt/state.tgz ~/

6. cd ~

7. tar xvf state.tgz

8. tar xvf local.tgz

So, you get an etc folder now. Go to /etc/vmware

9. nano esx.conf

10. Find /device//owner = "passthru".

Replace passthru with vmkernel.

11. Save the file

Now let’s copy the file back to the mount point, but first we have to recreate the archive.

12. tar czf local.tgz etc/

13. tar czf state.tgz local.tgz

14. sudo cp state.tgz /mnt/

15. reboot
