Hi, --verbose please. Do you see the same hang?

Hmm...it should have added change only in the error path, leaving locks for drivers to release if job is done with no error returned. > As far I know it is the qxl drivers's > job to call ttm_eu_backoff_reservation().

Xorg hangs in kernelspace with qxl
Hello! I'm experiencing the following task hangs at least 2-3 times a day when using a Kubuntu desktop in KVM via a SPICE client. This has occurred with the stock kernels in Kubuntu since Kubuntu 18.04. This makes the VM unusable as a graphical remote desktop and the hung task prevents Kubuntu from gracefully rebooting (e.g. "reboot" via SSH). Any ideas? INFO: task Xorg:879 blocked

[Bug 1062] New: Kernel IPv6 event filtering not working
...aemon Assignee: netfilter-buglog at lists.netfilter.org Reporter: arturo.borrero.glez at gmail.com IPv6 kernel filtering seems broken in conntrackd 1.4.3 with Linux kernel 4.4. The test is simple: * configure a two node conntrackd cluster to sync connections * configure IPv6 kernelspace filtering * launch `conntrack -E' to see conntrack events in both nodes * launch some IPv6 matching traffic, and see it syncing to the other node * switch the config to userspace filtering * launch some IPv6 matching traffic, the sync don't happen this time. This is an example configu...
