Hello everyone, I have a bit of followup on the USB3 issue on VIA VL805. After updating Linux kernel to 4.2.0-1 USB3 I was able to successfully copy bulk data using the front panel. In general the computer appears to be very stable, so I didn't bother with checking BIOS settings as the culprit was buggy USB3 kernel drivers.

Hello everyone,
I had to upgrade my old computer, and I can report a success with everything except VIA VL805 USB 3.0 host controller that locks up the system whenever I attempt to use USB 3 in Linux. Oh well. I have encountered that in the past with other USB 3 controllers. No idea what causes it.
Which kernel version do you have? I have found some discussions about a problem with some 3.1x kernels and 64bit mode on the VIA VL805 controller with IOMMU enabled.
And apparently it mainly affects seagate external drives.
See https://www.mail-archive.com/linux-usb%40vger.kernel.org/msg43326.html if interested. I run debian testing with kernel 4.2.0, last time I tried doing anything in linux was in 4.1.0. I mainly tested with a 3.5" front panel \w card reader, connected via USB3 header on the motherboard. The reader runs realtek-something chip (I will look it up when I get home). I'm able to boot debian USB image from bios, err, uefi, but when the OS

I found bunch of recent posts on debian, ubuntu and fedora mailing list dealing with very similar issues which leads me to believe it's not related to hardware.
I tweaked with IOMMU settings for a bit, I had to enable it to get keyboard and mouse to work during the install, but I changed settings afterwards, I will verify this. --- Talk Mailing List talk@gtalug.org http://gtalug.org/mailman/listinfo/talk
