184.108.40.206 is now available.
I've flogged the 220.127.116.11 kernel hard (compiling code) for the last week or so with no hiccups. So I'd say the .39 series is in real good shape.
For everything besides Dreamplugs:
sudo ./README-PLUG-UPDATE.sh 18.104.22.168 --nandkernel (installs 22.214.171.124 to nand)
sudo ./README-DREAM-UPDATE.sh 126.96.36.199 (installs 188.8.131.52 to disk)
Kernel and modules are available from the following locations:http://www.plugapps.com/mirror/with-linux/http://sheeva.with-linux.com/sheeva/
