Ugh, that's bad.

I haven't had a report of a page fault in quite some time. I'll have to look at your log files in more detail and see if it's a past bug resurfacing in Ubuntu's 3.2 kernel. How reproducible is the bug? > As attached files you can find lsusb -t and lsusb -vvv as well as lspci > and a picture of the screen with the kernel stack trace. Ok, I'll take a look at them and get back to you. In the meantime, can you compile the latest stable kernel (3.8.4), and see if you can reproduce your bug on that kernel? If you need help compiling a custom kernel, please take a look at these instructions: http://kernelnewbies.org/KernelBuild Please compile with CONFIG_USB_DEBUG and CONFIG_USB_XHCI_HCD_DEBUGGING turned on. If you can't reproduce your bug on 3.8.4, turn them off, recompile, and see if you can reproduce it again.
