Title:
64bit linux on gigabyte motherboards - IOMMU issue?
Status in “linux” package in Ubuntu:
Expired
Bug description:
I have a gigabyte GA-970A-DSP3 motherboard, and everything works fine with
32bit Kubuntu 13.10
After installing 64bit, the USB2 ports on the motherboard didn't work,
however the USB3 ports did work. The ethernet (motherboard) and wireless (PCI
card) wouldn't connect. They would recognize that the ethernet was plugged in,
and detect any wireless networks, but wouldn't connect to them.
One fix I found for this was to set IOMMU to enabled in the bios, then
the USB2 ports, ethernet and wireless worked fine, but the USB3 ports
stopped working.
I have found others with the same problem with varying models of gigabyte
motherboards and distributions of linux.
