Hi,
I'm in the process of transferring my home server to an Intel NUC. I've zfs
send/receive'd the whole pool to the new drive and first followed

You will find the pcap file attached.
FYI, I've tried to use "rdirplus" option from NetBSD NFS client as a
workaround but the mount stalls in UDP (works in TCP). If you are also
interested in this problem, I can
mbuf lists/alignment somewhat differently.)
I think I have to recompile my kernel, don't I? I tried to set

allows to interrupt the kernel in its current task if there is something
more important to do, like pushing a new sound frame. (If someone wants
