Hello, I think I am ready with the trace log. Hopefully it is full, because machine run out of disk space :) http://imperia.mine.nu/trace1.log.bz2 Interesting is that it took ~12 hours to crash it this time.
The problem with ssh access is that this is virtual machine under XEN and when you reboot it, the USB controller is gone(not assigned to virtual machine anymore). I have to re-assign the USB controller for passthrough from xen host. (this is xen bug I think, it wasn't like this before). This is what I do when I have to restart vdr virtual machine: xl pci-assignable-remove 03:00.0 xl pci-assignable-add 03:00.0 xl create /etc/xen/vdr.cfg Anyway we can get in touch on irc and I can do restarts for you. BTW, I shutdown the whole xen server. Then I turn off the power button on PSU and pressed the power button on the case to discharge any electricity left and put it in consistent state before getting the trace logs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1749961 Title: xhci_hcd: TRB DMA errors reported with ASMedia ASM1142 USB 3.1 Controller To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1749961/+subscriptions -- ubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
