Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

hi zev,

in case you upgrade to 8.4 and kernel 3.0.0 let me know if you will succeed!
I have difficulties to build drbd against kernel source!

Ken, Mark -- any further information on the write performance problem,
and/or a solution to it?

I'm running 8.3.7 at the moment, I think I'm going to try updating to
8.3.11 and/or 8.4 and see if it magically fixes anything (unless there are
further suggestions on other things to try).
