Reproducible: Always Steps to Reproduce: 1. Plug in some hardware with a PCIe bus and a Via VL800 chip. 2. Boot. 3. Gets here only if you're lucky. Actual Results: Many hangs while booting, depending on the moon, the system may not finish booting. It may work better with a CF card inserted into the reader when booting. Where I could get connection to the flash card or USB3.0 stick, it soon turned into an IO error with the flash device being disconnected by the driver. Once on oS 12.3 I has a solid oops, see screen shot attached. It seems that Linux support for VL800 is very flaky. http://askubuntu.com/questions/163227/why-doesnt-my-usb-3-0-pci-e-card-work-... http://ubuntuforums.org/showthread.php?t=1875917 My test device is PCIe x1 connected USB3.0 hub with card reader in 2.5" form factor.
