Hi,
Just thought I'd check here, I haven't had much luck on -stable. Is this
information helpful or do I need to get my remoted gdb stuff working to
give useful info? It would be nice to see any ata issues ironed out
before the point release. There still seem to be a decent number of
people having the "used to work, but now it panics" problem...
Thanks,
Charles

Hello,
I filed a PR on this, but I've been having trouble scrounging up parts to
build a null-modem cable so I can do a remote GDB trace on it. Since it
appears there'll be a 4.6.1, and whatever's broken in ata is still kind of
broken, here's what I can get from DDB (panic is before root is mounted):
ad0: READ command timeout tag-0 serv-0 - restting
ata0: restting devices .. ata0-slave: ATA identify retries exceeded
