As for stability in general, I think it's too soon to say how stable it is.
I built a kernel after yesterday's updates, and I built it on the
Dockstar itself so that's good.
Under heavy I/O to the TDK branded 32 gig USB stick, the device lags
pretty badly. Seems worse than just I/O performance on the USB stick,
but I could be wrong.
Someone mentioned earlier that rsync would hang. I have this problem
as well. netstat -i doesn't show errors. It just sits there. I haven't
looked any farther into it yet. This is what I do:
rsync -avx --progress <localfiles> rsync://me@server/rsync/repository/
I wanted to try another USB network adapter but when I plug it in
there's no phy. I noticed that the kernel config file doesn't have a
phy associated with USB ethernet adapters for whatever reason.
I also want to do some power testing. I was going to install FreeBSD
at some point to see how it works.
Does anyone know if Gentoo will run from chroot with the kernel that
the dockstar ships with?
