Hi, I'd recently reported an issue with kernel 3.14.4-1 'vs' USB3 -- call trace & no boot. A resolution was found, with patches Re: Fwd: xHCI regression for VIA USB 3.0 controller in handle_cmd_completion http://www.spinics.net/lists/linux-usb/msg108520.html I reported the problem to my distro, pointed at the patches from upstream, and a test build was done. INstalling that seemed to have resolved the problem -- in the 'test' repo. But, when the patche was supposedly included in kernel version upgrades from upstream, this was declared as (possibly/ Unfortunately, the problem returned with these update 3.15.1 kernels. Finally, an upgrade to today 3.15.2-1 incrementally improves again, and gets the system to boot AND the card to function, BUT the CALL TRACE is still present Bug 878489 - Kernel:Stable (3.15.2-1.gfb7c781) + USB3 (xhci_hcd) card throws CALL TRACE, completes boot https://bugzilla.novell.com/show_bug.cgi?id=878489 So, the system's healther, but not healthy. What additional info can I provide -- either to upstream here, or to my distro -- to help get this fixed?
