2.6.37 is now available.
Consider this a testing release. They reworked the nfs code in .37 and seem to have broken nfs client side support. I'm not sure if it would work as an NFS server, but judging how it works as a client I wouldn't trust it.
I'm still recommending using the .35 kernels for now as they seem to be good as gold.
Plugapps is now mirroring the kernels on a nightly basis, so kernels won't typically show up there until the following day after the announcement. They do have much more bandwidth than I do, so it's probably preferred to get them from Plugapps. The README files attempt to download from Plugapps first and then fallback to sheeva.with-linux.com.
Kernel and modules are available from the following locations:http://dev.plugapps.com/with-linux/http://sheeva.with-linux.com/sheeva/
Features e-sata, dmcrypt, IPV6, CIFS, NFS4, EXT3, EXT4, JFS, XFS, FUSE(for ntfs-3g), UBIFS, usb-serial, uvcvideo, iptables, appletalk, bluetooth, v4l and ppp.
