March 28, 201610 yr Trying to set up unRAID 6.2 on the following hardware: Gigabyte GA-EX58-UD5 using a bios version someone else received from Gigabyte to add a menu to enable VT-d i7-920 6 GB Ram XFX R5-220 in X16_1 Gigabyte GV-R478D5-1GD in X16_2 Intel 530 SSD and a host of other HDDs If I leave VT-d disabled, unRAID will load. If I enable VT-d, unRAID stops with this on screen: Unpacking initramfs... Freeing initrd memory: 129500K (ffff880078189000 - FFFF880080000000) DMAR: Host address width 36 DMAR: DRHD base: 0x000000fe711000 flags: 0x0 DMAR: dmar0: reg_base_addr fe711000 ver 1:0 cap c9008010e60262 ecap f0207a DMAR: DRHD base: 0x000000fe710000 flags: 0x1 DMAR: dmar0: reg_base_addr fe710000 ver 1:0 cap c90780106f0462 ecap f020fe DMAR: RMRR base: 0x000000cfef0000 end: 0x000000cfefffff DMAR: No ATSR found DMAR: dmar0: Using Queued invalidation and it stops here. I have been able to run 6.1.9 successfully, but am having issues with VMs, but that's for another post.
March 28, 201610 yr Do you have any Marvel disk controllers? It seems they have issues with vt-d/iommu. If so, you will need to do firmware updates for the Marvel controller.
March 28, 201610 yr Author According to the manual, I have 6 ports on an Intel® ICH10R, and 2 ports each on 2 JMB322 multipliers coming from a Gigabyte SATA2 controller. I also disabled the secondary controller in BIOS and still had no luck.
March 28, 201610 yr Just my guess, someone at Gigabyte updated the BIOS to enable vt-d, but hasn't finished... hasn't updated it enough to actually work! Keep checking for further BIOS updates, or switch to a different board.
April 9, 201610 yr Disable your onboard sound. I'm using an ASUS P6T Deluxe v2 (x58 chipset) and got the same screen as you. 6.19 worked fine with VT-D, but not 6.20/6.21
July 10, 20169 yr I'm having the same error, using an ASROCK X58 Supercomputer, disabled the onboard audio, no luck...
