Been seeing that on 6.2, also, though I've not noticed them locking up (the ones that have were in a cluster, and someone could have hosed memory). It got less with the latest kernel, but I'm still seeing them occasionally.
This is most likely a problem due to data arriving too quickly for the VM subsystem to flush dirty pages to disk to keep up; the kernel switches to synchronous mode when the dirty_ratio percentage of memory pages is used. You might try upping your dirty_ratio, or reducing it drastically.
But mine are *not* VMs.
VM = Virtual Memory.
Sorry, VM (virtual memory) is *so* different than VM (virtual machine), and in such a different context, dunno how I could have confused the two.... <g>
I'll try that, though IIRC, I've seen blocked tasks with someone running emacs.
