I tried both 2.6.37.1 and 2.6.35.11
2.6.37.1 is running ok on my guruplug, but for some reason the guruplug crashed last night, not sure what caused it.
Now running 2.6.35.11 and it works like a charm (also the added feature). The performance is very nice and very stable so far.
I might try 2.6.36.4 this week.
Thnx a lot and keep up the good work.
The .35 kernels are my goto version when I want ultimate reliability. I had tried .36.3 but had a few unexpected crashes. .37 didn't work reliably as an nfs-v4 client until .37.1. I'm sure .36 and .37 will get better over time, they're already better than they were.
