Created attachment 136901 [details] some output from console I have a random freeze when bacula running tasks, or when rsyncing. Please help me what i need to do to help you debug my problem. I run kexec -p /boot/kernel-genkernel-x86_64-3.14.4-gentoo --initrd=/boot/initramfs-genkernel-x86_64-3.14.4-gentoo --append="root=/dev/sda4 dolvm single irqpoll maxcpus=1 reset_devices" and waiting for freeze to do a kernel dump. I do not realy know what subsystem have a problem.

I'm batch-closing all xfs bugs which are more than 1 year old, sorry about that. If you still have this issue on a current kernel, please retest and re-open with this information. Thanks, -Eric
